I have a problem with Devexpress last v.48 and AlphaControls 2009 v6.53.
If AllowExtBorders := True, if You try to click the popup calculator or popup date selector, all the controls in the form flickers. If You set AllowExtBorders := False no flick anymore…
With Office2007Blue skin the month in popup calendar, when mouse is over, is withe and is not visible.
