Sorry-Repeat From Friday - Version 6.0.2CF1 and XP and radio button field

Sorry for repost - but I posted so late in the day Friday I thought perhaps I missed anyone seeing this. I have one radio button field that suddenly stopped working a week ago. I suspect it has something to do with users who have moved from Windows 2000 to XP Pro. Has anyone experienced something similar? If so, how do I get that field to show again to the XP folks? Should I simply delete it and re-create it? The rest of the form is working fine, and all fields are showing as programmed. The radio button has no hide-whens associated with it. Thanks for any help pointing me in the right direction! Cathy

We have lots of XP and I have not heard anything like that. Are you sure it is affecting the XP folks only?

Subject: Yes, appears to be XP only

I have a testing desktop that is on Windows 2000 still and no other users are complaining - our company is SLOWLY moving to XP - so right now it is only affecting perhaps 5 people instead of 300 but I cannot figure out what the problem is. I checked to make sure that the database moved up to the right version when it moved from 4.6 (where it was created) to the 6.0.1CF1 as per instructed last week. Cannot think what else to do. Thanks Doug for your response.
