How to repeat:
Trying read or write in protected memory

Thank you for the report.

I can not repeat described behavior. Please try latest version 5.2.26 and if problem still exists provide step-by-step instructions how to repeat the problem: do you connect to local or remote server, which table do you query, which query do you use, how many rows it returns.

Good Morning Sveta

I already use the version 5.2.26CE in my PC.

The bug occurs when I give a refresh in the first time that I execute Query.
After that I realize the Query again and press Refresh button and the Bug don't occurs. It's only the first time when I press the refresh button.

But this bug don't disrupts my Job.

I liked so much this new version.

I put the Mysql and the tools as the best I have ever used.

Very good.

Thank you for your attention.

Have a nice day.

Daniel

Daniel,

thank you for the feedback. I could not repeat the problem using test query on test table. Please clarify:

- do you connect to local or remote server
- which table do you query (output of SHOW CREATE TABLE)
- which query do you use
- how many rows it returns.

Hi Sveta

I connect using a remote server.

I use SHOW CREATE TABLE

I use JOIN and return me 1000 rows that is default

And I noted one think, when I do a query and press ctrl+shift+enter return me the results, and I wait over 15, after that I click on the refresh button and the error occurs.
