There are sometimes weird characters in an entry-widget. I cannot delete them but they disappeared after scrolling the text in the entry. We have made a temporary fix for this but cannot guarantee it works on every platform. If the hotkeys behave strangely, make sure you do not have previous bindings for them in your window manager. Activating the menus with accelerator-keys Version 4.2 of wish seems to have a bug with this.
Problems occur at least with the pop-up menu and the width of the listings.
Sometimes, after clicking an ActionButton or trying to execute extension binding, X-Files freezes totally. This happens if the program you are trying to run requires some input from you. Since we do not have any input stream to that process, it waits forever. X-Files v2.00 will have improved handling for this kind of situations.
