When I was adding new columns to a table I got the following error a few times when navigating between cells (Name, Datatype and Length/Set) with TAB: date/time : 2010-10-22, 17:42:08, 781ms computer name : xxx user name : xxx registered owner : xxx operating system : Windows Vista Tablet PC Service Pack 2 build 6002 system language : Polish system up time : 44 minutes 1 second program up time : 49 seconds processors : 2x Intel(R) Core(TM)2 Duo CPU E8235 @ 2.80GHz physical memory : 889/2028 MB (free/total) free disk space : (C:) 16,94 GB display mode : 1920x1200, 32 bit process id : $15e4 allocated memory : 55,17 MB executable : heidisql.exe exec. date/time : 2010-10-22 17:07 version : 5.1.0.3568 compiled with : Delphi 2010 madExcept version : 3.0k callstack crc : $bb969e7e, $556f25cc, $556f25cc exception number : 1 exception class : EAccessViolation exception message : Access violation at address 00621407 in module 'heidisql.exe'.

Heidi seems to continue functioning after pressing 'continue'. |

This is what issue #1677 reported. Very mysterious. Tried to fix that for the third time, without any luck. Does only occur in the table editors column list - nowhere else. |

Recently I had a similar one on build 3579: date/time : 2010-11-05, 18:24:03, 781ms computer name : xxx user name : xxx registered owner : xxx operating system : Windows Vista Tablet PC Service Pack 2 build 6002 system language : Polish system up time : 2 hours 16 minutes program up time : 46 minutes 49 seconds processors : 2x Intel(R) Core(TM)2 Duo CPU E8235 @ 2.80GHz physical memory : 848/2028 MB (free/total) free disk space : (C:) 13,44 GB display mode : 1920x1200, 32 bit process id : $152c allocated memory : 79,71 MB executable : heidisql.exe exec. date/time : 2010-11-04 17:01 version : 5.1.0.3579 compiled with : Delphi 2010 madExcept version : 3.0k callstack crc : $8554e145, $bb41deaa, $bb41deaa exception number : 3 exception class : EAccessViolation exception message : Access violation at address 00405748 in module 'heidisql.exe'.

I don't know if these bug reports tell you anything useful - hopefully you will be able to solve the mystery. |

See the call to TBaseGridEditorLink.TempWindowProc at least both AVs have the same cause. If I only knew how to fix that. Really mysterious stuff here. |
