Just tried 1.6 again today and I'm also having the before-mentioned bog down problems in IE and Windows.

I want understand what I'm reading. If I untick SDHelper in Spybot will that help the Windows problem as well as the IE problem? If not, do I need to untick TeaTimer too?

And, if I untick SDHelper, what am I sacrificing? Wouldn't it be more secure to stay with 1.5.2 for the time being?
