Maybe he should try to NOT use IE... if it doesn not work with any Version of IE it *might* be a bit rash to conclude that it will only work with IE...
Except for a few javascript commands that work only with IE (and are not recommended to use anyway) there should be no problem when using any other brother than IE.

The real problem might be, though, a corrupt database or invalid entry - undo turn only half done with some flags still set that make PBW refuse to accept a new turn, for instance. But this could only be solved by Geo himself, and may not be simple.
