Using iView 3.13 on Win XP SP2, I have always had this problem and it's getting quite frustrating. Basically if I am editing the keywords of a single (or multiple) images and try to delete 4 or more keywords, iView crashes immediately. I don't have a chance to "apply" my edits by hitting return or clicking the "Tick" (confirm) icon, the crash occurs as soon as i press delete on the 4th keyword.
Deleting one, two, or three keywords seems OK - it's almost always the fourth. Sometimes I just get a **BLANK** error dialog and can continue in iView, but typically I am thrown immediately to the desktop with a standard "iView encountered an error..." screen.
Anyone else have this problem?
