The only reason I even got involved with this thread was because Khaled said this...
I changed the bitmap loading method in mIRC 6.31 so that it no longer used video card memory (or at least, tried to avoid it). This resolved the background picture issue. However, it has clearly had an effect on display speed.
... which made me think that maybe it was related. My reply was to Khaled, not Riamus2 or foshizzle or anyone else. Maybe he should clarify whether he meant display in general or picwins only.
