Using Visual Studio 2010 C#, I switched from 32 bit to 64 bit Windows 7 . If the code broke under the 32 bit OS, it would stop and display the error message. Now with the 64 bit OS, when the code breaks it gives no message and just skips to FormActivate of the last form opened. Does anyone know how to make the 64 bit OS stop where the error occurred and display why it broke? Is there a switch?
