Strange issue on Windows Vista

[Andre Rombauts]

Hello from the cold and snowy Belgium...

I'm developping On Snow Leopard Enterprise 4.5 an application using  
MySQL libraries. The guy who is testing for me the Windows standalone  
reports that it is OK on XP and Windows7 but not on Vista. On Vista he  
is getting the error

Object: stack "revExternalLibrary" of stack "C:/Program Files/Chatou/ 
Chatou.exe"

I can generate a similar error if I remove the dbmysql.dll from the / 
database_drivers subdir in /Externals Is it possible to have issues on  
Vista and not on 7 or classic XP?
