Is there something wrong with 7 Beta? After installing beta versions of IE7 and Y! Messenger 7, all I have been doing is staring at alternate crashes! Looks like they have a pact or some sorta agreement to irritate and make me go crazy! If IE works for sometime, Yahoo crashes, and vice versa! Sheesh! Enough of all this crap! Should stick to FireFox and Msn I guess!
