Controls not displayed on auto-hide bars
Some controls when hosted on dockable auto-hide bars are not displayed when bar is flying out of auto-hidden state
DotNetBar uses the standard Windows API’s for bar animation when showing the bars from auto-hidden state. Some controls do not include full support for this functionality; in particular they do not handle the WM_PRINTCLIENT and/or WM_PRINT messages that are necessary for animation.
Solution: Disable DotNetBar animation by setting Bar.AutoHidenAnimationTime=0
