I just installed BibleWorks 9 (rev 4 DVDs) on Ubuntu 15.10 Mate Edition, but when I run BibleWorks it appears to hang. However, if I logout, then momentarily I can see that there was a hidden window asking to register BibleWorks, which, if I could have brought it to the top, I could have responded to it and I suspect BibleWorks would have run just fine. So is there any way I can bring that hidden registration window to the top? There are no "window handles" on the initial BibleWorks splash window with which to move it out of the way.
