Hi Herbalist, thanks for your list! When the crashes occur, it apprears to be independent of resources (At the moment, with IE and OE running, resources are 73/75/73). I routinely delete the dat files with CCleaner. Certain sites are a possibility, although it would be random, but I have not yet made any connection (I do not revisit the same sites that often). I typically only have IE/OE plus required startup programs running when I'm surfing (Startup: Avast AV, Sygate Firewall, Microsoft USB Mouse Driver). I used Spyware Doctor for some time but had to remove it for stability reasons. Now I use Spyware Terminator and Spybot for weekly scans. The problem occurred with SD and continues today. With regards to my IE file list, mshtml.dll should read ver. 1555. I tried the 1106 version for a couple of days and thought the problem was resolved but it turned out to be only wishful thinking. I also just noticed that I had two copies of the same version of iexplore.exe with different time stamps (???). I deleted the one that differed from your setup and we'll see if it helps. I would really like to test your mshtml.dll version 1528 (Appears like you didn't apply Update 916281). Could you provide it? Thanks again!
