Hello,

I have an app still in development using Borland C++ 5.01, and have
been doing some pro-active testing with XP Service Pack 2, release
candidate 2. When testing on a 64 bit machine, any Borland app built
with OWL using a main window derived from TWindow results in a Data
Execution Prevention error (the operating system stopping a program
that is attempting to execute code from a data page). This has been
traced to a the Windows API call "CreateWindowEx" in
TWindow::PerformCreate().

Does anyone have any idea as to what is happening or why, and if there
is a way around it while staying with Borland C++ 5.01? Data Execution
Prevention can be turned off for all apps or specified apps, however I
am trying to exhaust all other possibilities first.

Thanks.
