Biblesoft's PC Study Bible 5 is very buggy and frustrating to use. (I have the Professional version 5.0e.) It freezes at times, has access violations and crashes, looses "focus" that is, you can be at one location in the Bible and when you select another Commentary, instead of keeping at the same location for the new Commentary, it freezes all too often and goes way off somewhere else in the Bible. Clicking Cancel when given different options for a Commentary does not work necessarily.
The NavPanel on the left side of the screen has a tendency to "stick" open and not disappear like it's supposed to. It can be very slow moving through text on a page even with a computer with a 1.8 GHz Duo core processor. It is not completely Windows Vista compatible as when you start it, a warning is given that Vista will run in basic mode or something like that (You won't get all the visual effects.) It doesn't restore correctly from the task bar. It has all of these problems and perhaps more I've forgotten at the moment even though they came out with version 5 approximately one year ago.
Recently, I tried buying some software from their Website. It turned into a frustrating experience. One of several problems was that their Website automatically generated a password for me at some undetermined time so when I tried to log in, I of course couldn't. It also wouldn't send me the password either and so on, etc. It is very apparent, that they need to make sure their Website works correctly! Even after resorting to calling and ordering from a person, there were more problems.
The software does have good potential but the problems using it degrade the experience significantly. I am told that the owner or boss basically doesn't care that much so that is why it is like it is. Perhaps more constructive feedback will help make both the software and general customer experience better. (I have had previous versions starting at 2 or 3, I believe.)
