Rather than use WinResetClip, you should use WinGetClip to get your current clipping area, then create an intersection of that with your clipping rectangle using RctGetIntersection, and then call WinSetClip for the new clipping rectangle and use that when drawing your gadget. When you finish, call WinSetClip with the original clipping rectangle. Using WinResetClip during a frmUpdateEvent interferes with how the OS redraws stacked windows. -- Ben Combee <[EMAIL PROTECTED]> CodeWarrior for Palm OS technical lead Get help at http://palmoswerks.com/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
