>>>Perhaps a memory leak? Perhaps SYS(3050) to explicitly set memory buffer size might help? IIRC the memory management in the runtime gets sloppy when 2GB (or more) RAM is present.

>One thing I do recall is the return value from SYS(3050) could sometimes be negative (probably because it's returning a signed 32-bit value, so any amounts >=2^31 do not get reported correctly), so basically use something like:
>= SYS(3050, 1, 134217728)
>= SYS(3050, 2, 134217728)

Tried those, but no dice. I also blanked the config.fpw settings as we do in VMP and as advised here: http://rickschummer.com/blog/2008/06/vfp-include-configfpw-in-exe.html Still no good. It's even happening on my VM. I tried reducing the video resolution and removing the persistent bitmap caching.
BITMAP=OFF in the config made no difference. It's vfp6. It seems the app runs in 9 no problem and of course, it does not show this behavior in 9.
