Firstly, I agree with Redlemon that something may be going on with your extensions, or possibly a custom skin if you're using one. Also, if you haven't checked for adware or spyware, maybe youshould as htis is th ekind of odd behaviour that really sends up red flags that something is going on.
And Prgma's right too, it's just a bit of a pain in the arse to have to open TM everytime you want to quit a program. By the way Pragma, nice.sig you have there!
And here I am thinking that you were joking!
Peace,
