The cause of the recent crashes has been tracked down. Blackbox was holding a pointer to a window and that window was destroyed but the pointer was not updated.
Window A gets focus, Window B is opened and gets focus. Window A gets destroyed. Window B gets destroyed and blackbox tries to give focus back to A, which is not there. This is fixed in pre4, so the sylpheed/mozilla crashes should be behind us. Also in pre4 is a fix to a crash caused by user remapping Caps Lock, seems our no lock modifiers patch neglected to handle this. Blackbox now ignores backup files in the style menu (foo~ will not be shown) minor touchups elsewhere. Once again, this is considered a release candidate. We can either fix the bugs now or later (-:
