It looks like the problem is related to the project itself. I would try to recreate the project from the scrarch and see if it helps.
>Tried to switch to new WindowsXP mashine (384 MB RAM).
>Moved my VFP6 project (old OS - Win98).
>Having problem with rebiulding project or building exe.
>When do it right after starting Foxpro works fine. When rebuilding second time gives an error "The instruction at "0x77e6d756" referenced memoty at "0x00000000". The memory could not be "written". Next error "Unhandled exception in VFP6.exe (KERNEL32.DLL):0xC0000005:Access Violation".
>Terminate FoxPro, start again - the same thing - second build gives an error.
>
>Opening the same project in VFP7 - the same result.

>Help!!
