Lockup after Undo

[tshare]

Hello,

A couple times now Ultra Recall has locked up after I used CTRL-Z to Undo while I have a Word or Excel document open within the Browser in Ultra Recall. Now I know not to use Undo when editing a document in Ultra Recall, but it would be nice to not have Ultra Recall lock up when I screw up and do it.

Thanks,
Timothy
