Help. This has been happening tonight. Seems like everytime I open firefox/camino/safari; they all crash/stalled with the balloon ball spinning all the time. Sometimes my entire system freezes. The weird thing is that I can open and run other Non-web browser programs like iTunes, MS Word, Adobe Acrobat, Adobe Photoshop fine while the web browsers are still spinning and not responding. I tried to do some research and installed the Leopard Cache Cleaner but that did not help My macbook is only 1 week old and it's got 4GB of RAM. It's not a memory problem because the Activity monitor says I have more than 3GB of RAM available. I am not running any thing else. I have Mac OS 10.5.2. The only software I've installed is MS Office 2k8, Adobe CS3 Design Premium. I really do not want to do a clean install at this point.
