Hello
I have a vfp app that had been working OK for several years on w98 / 2000 against sql server 7 databases. When the user migrated their client OS to XP Sp1, some errors began to appear. Oddly, some of the errors are ODBC related (insertion of duplicated primary keys, null values, and the like, which do not occur on w2000!). Or the app just crashes (without C5 or any error - it just blows out and dissapears)

Then I migrated the development machine to XP to try to reproduce it (which I can running the exe-), and I cannot even open some forms from the IDE: the same forms that I had been working with , (VFP7 SP1/ W2k SP1) cannot be opened on XP (error loading file - gridx or one of its members - Height. Expression evaluated to an illegal value.).
I go to a w2000 machine and the app runs OK, the forms can be opened.

Any help will be appreciated... I am totally clueless...

TIA
