How to flush the SoundFont Cache

[12Kevin]

When I use the SoundFonts tool (under Tools) in Guitar Studio to attach SoundFonts for a song, they don't appear in the the SoundFont Cache utility provided with SBLive!'s LiveWare.

The memory allocation bar shows memory allocated for them, but I can't find a way to clear the cache. Resulting in occasional memory shortages.

Is there a way to flush the Soundfont Cache completely without restarting windows?

I will be so very grateful!
