If I remember back to my old Windows 3.1 development days, you could either redraw the Window [portion] directly on screen in response to a WM_PAINT (and not a WM_SIZE as I mentioned earlier!), or, you could draw it off screen and 'blit' it to screen thus reducing/avoiding the flicker. As for the Java lot, well, they seem to always want to re-invent the wheel anyway, so it doesn't surprise me that they have written their own (slow perhaps?) screen resize/redraw code. I have to deal with a lot of applications at work, written in Java (or even worse, Java for WebLogic!) and they always create 'new' code to do stuff that the backend Oracle database has been doing, quite efficiently, for years. I actually hate Java! :-) Cheers, Norman. _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
