message : Access violation

Hi; Love this software! Thank you for a very powerful work horse! I'm new to MySQL and HeidiSQL has been making my life so much easier.

I haven't been able to keep lately HeidiSQL stable, and was wondering why.

I was trying to reset the counter on my ID column by deleting ID and Saving the DB, and creating the ID column anew that way the counter - auto increase - would give me the right number for the column. Any way I got an error one time saving it and the software hasn't been the same. After trying several times to open this database the software crashed everytime. Only after a day it opened the database (it allowed me to same my work!) but I get the following error:

Access violation at address 007EDBAF in module 'heidisql.exe'. Read of address 0000000C.

1.) Why the error & how do I make it stop?
2.) Is there an easier way to reset the counter of the ID column?

Thanks for your help

Actually I can no longer access any data on that DB....
Here is the dump:

That code place are where I was currently working on, sorry to cause errors left and right.

I'll try to work around that conversion error asap. In the meantime, you can fix that for yourself:
- exit all heidisql.exe instances
- start regedit.exe
- navigate to HKEY_CURRENT_USER\Software\HeidiSQL\Servers\
- in each session subfolder, watch for a sub key calles "QueryHistory". Delete these keys.
- start heididql.exe

This is issue #2791, and I just fixed that in r4100.

Thank You! works fine now
