So I'm beginning to believe I'm the only one using MCT on a Mac around here
1.82 breaks compatibility because of the use of javax.swing.GroupLayout, which is only included in Java 1.6 and is currently in use on a few of the forms... the problem being that mmj (which is required so that Java can actually see the MegaDrum) only runs on 1.5 because that's the only 32-bit version. In fact I'm surprised more people haven't reported breakage, or maybe everyone is on 1.6 now.
However it's pretty straightforward to fix; would you like me to commit the changes so you can make sure it doesn't break anything else? (elrules: btw, the fix is to select the code generation style as 'swing extensions', not 'standard java 6 code' for the code generation in those classes which use the designer).
