Sanjay,

>==> We are using same machine for testing/comparing the EXEs of VFP6/VFP7 version. Client/testing machine have no source code. EXE of both version are made by single but different PC. So No chance for window display setting difference. However we are further looking deep into your suggestion.

Are you using different data between test and dev? I've never seen this size change, but I can't say that I've gone looking for a couple of pixel changes either.

>In different language operating system (say chinease) _VFP.version may not return 7.0 But (#@#@$).

I've never used a non-US version of VFP so I don't know how you might need to handle this. agetfileversion() might be a solution for you.
