unhandled win32 exception when Enter button is hit

Hi,

In my PB application, in one of the windows , the command button cb_ok is the default. During the run time, using the executable,

if we hit on Enter, the application is crashing with unhandled win 32 exception. At the same time, clicking on the command button is working fine.

Another strange thing is, the application is not crashing in the same scenario when run from Powerbuilder IDE. So I could not debug and understand the reasons for crash.

Can any one please advice me how I can attempt to find the root cause of this issue.

Best Regards,

Kiran
