BW stopping Windows from shutting down
I'm using Windows 7 Pro 64-bit. When Windows has updates to do that necessitate a restart of the computer and BibleWorks is open, I always get a message saying that BW is preventing Windows from shutting down. I either have to use the Force Shut Down button (which never seems to cause a problem), or cancel the shutdown and close BW manually. BW seems to be the only program that does this. Does anyone else experience it? Anyone know what causes it?
