Thank you for a problem report. Please, upload smallest problematic .mwb file and exact steps on how to repeat the problem with it. Do you have XP SP2 or SP3, 32-bit or 64-bit?

I also encounter infinite number of error windows saying "Attempted to read or write protected memory... when working with some of my schemas in WB 5.0.27 on 32bit XP SP2. How to repeat: When clicking on table Privilege I get windows saying "Attempted to read or write protected memory... When clicking on table Group I get Microsoft.Net Framework window with unhandled exception message plus these repeating windows "Attempted to read or write protected memory... and there are red crosses in Catalog and small canvas windows to the right. I send you the db file. Thank you

Hello, I am on Windows XP SP3, 32bit. The errors seem to happen when: Selecting a group of tables in Diagram View. Creating a new table in Diagram View. The errors usually happen after loading a .mwb file or period of inactivity. I found a way to avoid the error, is to simply click once on any 1 table to select it, and then click away to deselect. After doing that, I can select multiple tables or create new tables without the error happening.

Tomas Korc's db produced the same problem for me as I've been having. In my own schemas, I've found that the error also occurs after loading a mwb file with 41 tables, then clicking on a table in the Diagram view, then clicking on an empty area to deselect it. Error message pops up and same issue happens. I've been able to work around it by closing Diagram view, opening editor for a few tables, opening Diagram view, double clicking carefully on a few tables, and then usually the problem goes away for that session and I can work without problems. But once I close MySQL Workbench and load the same mwb file again, the problem reoccurs.

Many thanks for writing a bug report. I can't repeat this behaviour. Also not with idling more then 8 hours. I would assume this is a memory problem. How many RAM has your machine?

Hello, I have 4 gb ram in my machine. Tomas Korc's mwb file consistently produces the crash for me.. strange that it isn't doing the same to some other people. I'm running MySQL Workbench 5.0.27 SE. Bug happens so often (few times a day) that it makes it difficult to work.

A little more information about my setup.. in case this has any use. I'm running dual monitors with UltraMon, 1900x1200 and 1600x1200. I run MySQL Workbench on the 1900x1200 widescreen monitor. I wonder if other people having this bug are also on dual monitor and/or high-res screens?

Hello, as for the RAM, I encountered the problem on my notebook with 1,5 GB and also on PC with 448 MB at time of my first reporting. Somehow, this error happens less frequently in recent days and what is strange, I cannot repeat the error with the submitted file right now. I also use dual monitor configuration, both with 1024x768.

Many thanks for writing a bug report. Unfortunately, nobody of us is able to repeat this. Please try newer version: Workbench 5.0.29 and let us know if you still have this problem.

Hello, Yes, I'm still having this problem in 5.0.29. I will try to do some more extensive testing myself and write the step-by-step method and/or files that produce this bug.

I can reproduce this with Workbench 5.0.29 OSS. I took given from tomas mwb file. I opened it by just clicking on it. Not starting Workbench before, just let Workbench start by clicking on the file. I selected a few tables and got the German Windows Error message: "Es wurde versucht, im geschützten Speicher zu lesen oder zu schreiben. Dies ist häufig ein Hinweis darauf, dass anderer Speicher beschädigt ist." The English translation should be: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

I just made a HDD clean up and a disk check. For disk check I needed to reboot so that disk check was executed. After that I couldn't reproduce this error anymore. Please try this too and let us know if that helped. It really seems it is more Windows related then Workbench related.

Same problem to me - can reproduce it with this: - Double Click my.mwb - MySQL Workbench opens - everything is fine - right click on a table -> EDIT... - ERROR Workaround for me: - Double Click my.mwb - MySQL Workbench opens - everything is fine - left click on the table - waiting a few seconds - right click on a table -> EDIT... - no error, ready to edit And the error is coming up while doing other things with the workbench - but cannot reproduce them. I think I'm to fast with doing things. System: Dual Core 2*2,4GHZ 2GB RAM dual channel ATI x1950pro MySQL Workbench 5.0.30 OSS

Hi If possible, please check if this bug is still present in 5.1 BETA for Windows.

Please check with version 5.1 of Workbench. We are focussing on WB 5.1 and would like to fix this problem there if it still exists, rather than WB 5.0. Thank you.
