I do not have that problem, minimize/maximize no problem, but I had found the culprit in my case, it could be or not a "bug", maybe a windows listview strange thing or a missunderstood by my side. I had write a little test project and compiled also in Delphi 7. The test add 6000 entries, updates them, scroll from first to last, and delete them. The scroll flickers a bit more in Lazarus than in Delphi. My problem was the beginupdate/endupdate which many times only one line is updated/added/deleted and the endupdate forces a repaint which inserts more flickering than not using them. -- Best regards, José -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
