I have a VFP6 app that is mature, stable, and in wide distribution. Some of my users are beginning to get Windows XP computers, and on those computers, a grid in one of the app's forms is missing one of its column. I recently got an XP computer, and sure enough, same thing happens on it. I migrated the app to VFP7, and I still get the same behaviour. This screwy behaviour is absent on all other operating platforms--Windows 9x, Me, and 2000.

Have any of you experienced this?
