Now it is visually back to the situation before X12, lots of flickering.
I beg to differ. I've tried it, and it *sometimes* flickers *once* (that is, at the end of the download, it refreshes again, even if it shouldn't). Problem is, that the _app_ requires that behaviour! That is, it depends on WM_SETREDRAW(TRUE) to invalidate the list, and it's issuing one at the end...
What I see different from native comcontrol is that 1- during a refresh everything is redrawn, including the header control; 2- the refreshing continues about once every second until the download is finished, certainly not "sometimes" or only "at the end".
I will investigate the WM_SETREDRAW messages, perhaps they appear too often in my situation. That still does not explain why a refresh with native dll manages only to repaint the updated part, which is nill at the end of the download.
