Description:
When I try to modify a table, workbench crash randomly.
May times , If only open the model and move the table objects, do not ocurrs error and I can save the new table positions.

I don't know if my computer problem or specifically my model is corrupted.

Is not a large model, and my PC have 2GB RAM. 

How to repeat:
Open the model attached, and browse the model making double click in tables to edit them.

Sometimes open the model and changing to "My SQL model" tab is enougth to reproduce the crash.

Is really a phisical memory problem?, is going out of memory or crashing with other program?

Help please.

Suggested fix:
If really is a memory problem with my pc, handle the exception and Close the progrma softly.

Thank you for the bug report. I couldn't repeat the crash but I noticed when double click the tables the CPU usage arises to 100% and keeps WB freezing for some seconds. Changing between the MySQL Model and the Diagram Screen after a few double click on the tables is more aggressive the CPU usage. I attached a picture showing the task manager.

Is no easy repeat the crash, maybe my PC have a lot of importence in the bug.

I uncheck the option "Automatically reopen last opened model whem started" in the General Tab in WB Options, and the crash do not sucess.

Maybe there are a little diference between the automatically open and the manually open around the memory usage or something.

I check the option and the crash is repeated.

A mistery for me, but for now I left uncheked this option.

Thank you for the feedback. Now I was able to repeat checking the option "Automatically reopen last opened model whem started".

Great!!.

Then is no only my PC.

Maybe the model is corrupted else a WB bug.

Thanks.
[24 Feb 2009 12:04] Rodrigo Olivares 
Fixed?

Seems to be corrected in 5.0.30.

Thanks
[4 Mar 2009 11:31] Rodrigo Olivares 
Correction, same behavior in 5.0.30.

Thanks

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.

I started having this problem after a power failure. It crashes when I connect (double-click) on the "local instance", I can start a new model and open the server admin with no problems. If I choose "command line" everything is fine, and I can work perfectly.

I have Win7-64, MySQL 5.5, and WB 5.2.34 CE 7780
