I'm going to guess...
If you have a virus checker running when you install the framework for the
first time, sometimes the controls in the framework cannot register
properly, which makes them misbehave. I've heard of folks who start their
apps on one customer's machine, and no buttons at all are visible on the
form, or other control anomalies. Can you have these customers download the
framework from MS, but then, before they reinstall it, turn off their virus
checking software? Then, reinstall the framework. This may fix the
problem. (this is a guess... I am not certain that this will work.)
