Hi Pritpal,

Synchronized with GTWVT per Viktor's changes for box characters. > ! Commented out previous change per Przemek's "Layered Attributes". This was originally my addition, but Przemek was nice to commit it on my behalf. Anyway, I think you should look for some more information regarding "layered window" mode, because one of it's points is to reduce flickering and unnecessary redraw requests. You ask Windows to manage the bitmap and you only need to update it when a real update occurs (but not, when the window is just moved around or gets focus). So this isn't a magic switch, and you may need to tweak the way WVG windows are updated to exploit it's possibilities in a good way. This link is good for a start, but probably not enough to finish: http://msdn.microsoft.com/en-us/library/ms997507.aspx [ Surprisingly Vista removed support for layered windows, so it may also happen that we should tweak this feature when running under Vista. I've already turned it off for TS mode, because of bad performance. ] Brgds, Viktor
