Category:	MySQL Query Browser	Severity:	S1 (Critical)
Version:	1.1.20	OS:	Windows (Windows 2000)
Assigned to:		CPU Architecture:	Any

Description:
I had a problem with ver 1.1.19 getting error message: "access violation at address 005bc79c in module 'MySqlBrowser.exe'. Read of address 00000000"

so i upgraded to ver 1.1.20 now 

I can connect okay to the MySql server (ver 5.0.18)  but when the main Query Browser window open i get the following message. Error: "access violation at address 005bc7b4 in module 'MySqlBrowser.exe'. Read of address 00000000"

I have run version 1.1.19 and 1.1.20 under windows xp sp2 professional with no problems.

How to repeat:
Open "Query Browser" connect to Database server.
The main program windows then locks with the above error displayed at the bottom.

Thank you for a problem report. Have you installed QB on Windows 2000 as local Administrator?

Yes, it was installed under the local built-in administrator account.

Do you have any service packs/antivirus software/firewall software installed on Windows 2000?

I get the same problem on XP pro SP2. Tried a back version (1.1.14) and had the same problem. I erase all the history files, do a complete uninstall of the tools (not the database) with no change in outcome.

This bug has been around for years, looking through the bug repository. It is hard to provide more detail, other than when the main Query Browser window appears, the error is shown repeatedly in the status bar.

It makes it impossible to use the tool on systems that have this problem. I agree it is a critical problem, it is frustrating that it has been around so long.

I had service pack 4 installed and some of the other security patches. I have now installed the latest security patches (4 in total) and rebooted this server.

The Query Browser software is now running correctly.

Many thanks for your help.

Closed as bug does not occur any more after OS upgrade.

As I just reported for bug #4329 I also get this in 1.1.20 .
I have removed all the xml files (but not reinstalled QB), but I haven't gotten
rid of it. After I startup (no database) my processor untilization jumps up to
about 80% and stays there. When I click on a menu or in query tab the
untilization sinks to 0%.  But it will jump right back up, at yet not identified
moments.
If I right click in the tree, the first time it only displays for a fraction of
a second before disappearing. The second time seems fine.
(We run MySQL 4.1.11 on Linux and an ODBC 3.51 connection.  I also have MySQL
Admin on my PC with Win2000 SP4.)
