Although its not a permanent fix, the following might help you as a temporary workaround.
After minimising the 'Front Panel', and later restoring it:-
Switch over to the 'Phantom Frog' window,
Un-Tick the Check Box next to "Show Front Panel",
and then Re-Tick it.
The 'Front Panel' Window should blip, and re-appear refreshed and raring to go. :wink:
I hope that helps.
I generally find myself using this method to hide the 'Front Panel' instead of minimising it, as it kills two birds with one stone.
NB: No birds were harmed in the making of this post.
