This is crazy. I've been using my 2008 MBP for years without a problem. Last week, the trackpad began acting funny in that it wouldn't allow me to highlight text in order to cut & paste etc. The trackpad still worked fine in every other regard, but I started getting beach balls very regularly, even when I didn't have many applications opened at once (and sometimes when only Mail and Safari were running). Now, from out of nowhere, the trackpad isn't registering hard clicks at startup and I cannot get past the initial screen where I would normally select a user profile. The trackpad is still registering movements (I can move the curser anywhere) but I can't click on a user profile to get anything started. No idea why this is happening or what I can do. Has anyone got any tips or ideas?
