Could you please check the following directory.

C:\Documents and Settings\YourUserName\Application Data\MySQL (on a german box C:\Dokumente und
Einstellungen\Mike\Anwendungsdaten\MySQL)

This is where the settings for the MySQL GUI tools are stored. Please zip the directory to have a backup and then remove all mysqlqb_* files (the files for Query Browser) and maybe also the mysqlx_* files (the common files shared by all GUI tools).

If QB starts correctly, please copy back file by file to see which one is currupted. If possible (and the file does not contain confidetial
data) please attach this file to the bug report so we can trace the problem in the source and fix it.

We would appreciate this a lot, thanks in advance, Mike

Description:
The Query Browser seemed to work fine till I tried deleting rows from a table. After doing this, I got an error (cannot reproduce the error now). 

I closed Query Browser, and tried re-opening it, and got the error : 

"Access violation at address 003BB920 in module 'libmysqlqb.dll'. Read of address 00000000"

The window which displays query results was transparent. 

I tried various things : 

1. Reparing Query browser by re-running the msi. 
2. Removing the installation and re-installing. 
3. Dropping the catalog and re-creating. 
4. Re-downloading the msi from mySQL.org and re-installing. 

However, I always get the same error.




How to repeat:
Try deleting a large set of records in query browser.
