Question on Property Page.

hi all!

In my property sheet-based application, I have a few property pages (tabbed dialogs), each with a few buttons on it. Okay. The problem is sometimes when I go to another page/tab and returns to the previous page, the buttons are missing! It seems that they are not 'refreshed'. Even when another application window covers my property sheet apps, those buttons disappear. I can still get the buttons functionality by clicking around where the buttons are supposed to be. Please advise.

thanks for your help.
