[Wine] Microsoft Pinball problem

[Doug]

Some time ago, I installed Pinball in Wine. It worked as it was supposed 
to--push F4 to get full screen.  Now if I push F4, I get a BLACK
full screen, but the game remains small in the middle--it never gets any 
bigger.  What can I do to get it to work right again?  (If I
must uninstall it and then get a new copy, please tell me how to 
uninstall something in Wine.)
Thanx--doug
