I had something similar happen to me in VFP5:

I believe in my case it was subtle corruption in a .VCX. IIRC I had to copy the .VCX contents out to a new one (USEing it as a table) then rename appropriately and COMPILE the classlib again.

Before doing that you could manually edit your .VCX and check for bad/extended characters at or near the lines of code causing the problem.

Be sure to back up before hacking your .VCXs!
