Here is some code I personally use for window resize. It's rather quick to see that InvalidateRect would force a repaint of the entire Window. Possibly (not haveing looked first) that the library you use to handle this is forceing more than one InvalidateRect or haveing a Paint event tied closely to this.... When I use the routine (below) to resize windows, even on a somewhat slow 233mhz machine, I experience 0 (zero) flicker........tested with 20+ controls in the client as well.... </snip> elsif iMsg = WM_SIZE then inc = HIWORD(lParam)-peek4s(rect_Bottom) if inc > 0 and orgY >= vyScreen-peek4s(rect_Bottom) then orgY -= inc end if if orgY < 0 then orgY = 0 end if inc = LOWORD(lParam)-peek4s(rect_Right) if inc > 0 and orgX >= vxScreen-peek4s(rect_Right) then orgX -= inc end if if orgX < 0 then orgX = 0 end if c_proc(GetClientRect, {hwnd,rect}) poke4(sifMask,or_bits(SIF_RANGE, SIF_POS)) poke4(sifMin, 0) poke4(sifMax,vxScreen-peek4s(rect_Right)) poke4(sifPos,orgX) ok = c_func(xSetScrollInfo,{hwnd, SB_HORZ, si, 1}) poke4(sifMax,vyScreen-peek4s(rect_Bottom)) poke4(sifPos,orgY) ok = c_func(xSetScrollInfo,{hwnd, SB_VERT, si, 1}) return c_func(xInvalidateRect, {hwnd, NULL, 0}) <snip/> ck, your answer about the window being smooth in the demo I sent you answers my question about your hardware. There is nothing wrong with it.....Its must be your code or the library you are useing! Euman euman at bellsouth.net
