I changed the jdk.config files as suggested on a few different installations of JB7 Personal and Enterprise Edition, and while it did add wheel mouse support in the code view mode, it did not add wheel mouse support in other views (such as
doc). The bigger problem concerned weird behavior of the code pop-ups (the keyboard would become... ignored to a large extent) which was experienced on all
test installations. I undid the changes and the problems disappeared. I haven't had any problems with the free open tool mentioned above.
