[QUOTE="bargz"]\nI have Windows XP SP3, and I decided to install Internet Explorer 8\nlast week. It installed fine, and I used it for a week, but my\ndesktop UI speed had become NOTICEABLY sluggish: when I move\nwindows around, there would be a white "lag" behind them, similar\nto turning on "mouse trails" for your cursor. It acted like I had\ndisabled video acceleration. Also, YouTube videos were jittery and\nmy CPU utilization was very high while watching.\n\nThinking it may have been outdated NVidia drivers, I downloaded and\ninstalled the latest release from NVidia's web site, but the\nsituation did not improve.\n\nI've searched the web and the newsgroups and cannot find anyone\nwith a similar problem; I found some people complained about\nsluggish WEB PAGES with IE8, but my issue is not that web pages are\nslow to load, but specifically it's a problem with my GUI rendering\nspeed.\n\nAnyway, this morning I uninstalled IE8, rebooted, and now my GUI\nspeed is back to normal (fast) -\- I can move windows around without\ntrails -\- so it is obviously something with Internet Explorer 8.\n\nMy system specs:\nDell 400SC\nPentium-4 HT 2.8GHz single core\n3 GB memory\nNVidia GeForce 7600 GS 512MB AGP 8X, driver version 185.85\nDual LCD monitors\nWindows XP SP3 with all high-priority updates\n\nThoughts? Anyone?[/QUOTE]\n\nJust for the heck of it...\n\nIf in XP, just do this:\n\nStart button -\-> RUN -\-> type in:\n\nregsvr32 actxprxy.dll\n\n\n-\-. Click OK.\n\nReboot.\n\n\nIf Vista, you need to open a command prompt as the administrator (run as\nadministrator) and run the following command:\n\nregsvr32 actxprxy.dll\n\n\n\nReboot.\n\n\n\nHelp any?
