Known Problem with Finale 97/98
(plug-in menu items not responding)
 

Due to the many plug-ins contained in TGTools, this may exceed the limit of plug-ins that will work with these older versions of Finale. If you experience problems accessing TGTools menu items (such as no reaction), you need to remove other plug-ins that you don’t need from Finale’s plug-in folder. In fact, you may need to remove quite a few of them, until all TGTools items work.

A better solution is in the works but not available yet.
