I don't think there's a setting that could be causing this (though I certainly don't know everything about the settings!). I had a similar problem at one point (http://www.bibleworks.com/forums/sho...th-context-tab). The BibleWorks staff came up with a fix very promptly. But it's important to know as much about the situation as possible. What version of BibleWorks are you using? (Use Help > About to get the precise number, including updates.) Are there particular Bible versions that this happens in? What else do you have open at the time, such as tabs in the Analysis Window? Randomly occurring problems like this are hard to reproduce, and therefore hard to fix, so having all the data will help them.
