An update on this problem with ZynAddSubFX on F7, And F8 using KDE. I posted a 
bugreport for it, and Anthony Green suggested it may be a problem with fltk.

So I removed fltk-1.1.8-0.4.r5750.fc8.i386.rpm, along with Zyn from Fedora 8. 
mThen installed fltk_1.1.7-1.fc5_i386.rpm, followed by reinstalling Zyn.

Now ZynAddSubFx is working ok on Fedora 8, and I expect the same procedure 
will work on Fedora 7.

As Anthony Green suspected, it appears to be an fltk problem, but only with 
some graphics cards perhaps, as you "Mysth-R" have said that Zyn is working 
ok on KDE for you.

This is just an update, and now back to bugzilla.

Nigel.
