Paint & drawreversibleframe

Hi,
i'm submitting a problem with the drawreversibleframe.
I got a user control wich uses the controlpaint.drawreversibleframe to draw selection rectangle whith mouse action.
Everything OK as the control doesn't repaint.
I got a timer that invalidate regularly the control and the frame are erased.
I tried to include the control in another and to catch selection in the parent. The result is the same, each painting erase my frame.

Any solution?

try to override the drawbackground and cancel the event...

Thanks for reply,

I was thinking about canceling the event during selection time.
I'm going to try this way...
