I have deployed a infopath 2010 form as an administrative template and attached it in the infopath webpart. It was working fine , until now all of a sudden the form fields get cleared out. I cannot write anything on the text box, comboboxes all are behaving weird, radio buttons get cleared out automatically. This behaviour I have noted with a lot of users which have windows xp and ie 8, even if i revert ie 8 to 7 the problem remains. However I dont see this behaviour while i try to open these forms on firefox or chrome and the form opens correctly in other browsers.
What is the best way to look into this issue. We have userbase of above 1000 and we are starting to see this problem hit counter increase everyday ? It looks like a post back problem, but the strangest thing is it was working before on these machines and it stopped working. We ve not made any changes to the template. I doubt if there are some group policy settings or IE related hot fixes that are triggering it.
