Why doesn't my mouse wheel work for scrolling in VAJ?
FAQ Manager's Comment: Getting mouse wheel scrolling to work in earlier versions of VAJ (2.0 and 3.0x) is possible. One thing that might help is to make sure that you have a recent version of your mouse driver software installed. For example, it seems that some versions of Miscrosoft's IntelliPoint software do not work properly with all applications (VAJ included), but some versions do.
Also, understand that mouse wheels do not work in Java AWT/Swing programs at all. Since certain parts of VAJ are actually running Java programs (parts of the VCE, for example), the wheel may not work in those parts.
