I don't think it is a priority issue, but possibly may be a caching matter when several apps are open at once. If Bible Analyzer responds slow when using it, it is usually because a lot of modules are loaded. If that's the case one can use Session Manager to break them up into groups for quicker response.
I have a Mac Mini with 4GB of ram and if a lot of modules are loaded, such as all those on the CD, the response is a little slower than just the standard modules embedded in the download, but I usually don't have many other apps running either. When I get a chance I load up a few more apps and switch between them and see what happens.
