I build all CButton, CEdit, CTabCtrl and so on dynamically and so far
all looks good.
Additionally i am using CWebBrowser2 (IWebBrowser) control.
Often all controls redraw fine, if i'm closing a hiding window or click
a tab, only the web browser control doesn't sometimes and i cannot
reproduce exactly why and when.

Seems to have something to do if i invalidate twice?!

Any hints?
