thanks, SetSel only has 2 parameters.. anyway i meant even if the selection was at the end of the text it still tries to scroll it in its way (like line by line) which causes the flicker, when i try to force it stay down it first goes up one line and then down i hope this made sense.. if not please tell me and ill explain again :P if there was a way to slow down the PC a lot or just the application you could see it very clearly whats happening lol btw i dont think i have said this before.. but if you look at MSN Messenger you will see that it doesnt have any flickering problem and im pretty sure it uses the rich edit control.. but yea its made by microsoft so they know the rich edit's secret lol but theres also GameSpy Arcade.. which works without a problem i dunno how they do it.. all i see is that they put in a custom scrollbar.. but i dont see how that helped this is because of auto vscroll, actually really check this out.. remove the auto vscroll property and it will never flicker.. you have to remove vertical scroll as well..
