I've got a 250 gb iMac G5. I've used about 70 gb of HD space and last night while I was watching a DVD I got two separate popups for separate applications, one saying that my startup disk was full and stuff needed to be deleted. Then another later, don't remember which app, but I hadn't opened it and said that my hard drive was full. This morning I got another one from Entourage saying that it was closing because I had no HD space. Funny cause I'm still only using about 70 gb, I didn't open entourage today, or ever for that matter. I did a virus scan (even if it was unlikely) and came back all clean, emptied my trash, etc... Any idea what is going on? I've also been having problems with Safari since about November when I updated it. It frequently closes with an error message or freezes, although that doesn't happen as often as the first. So anyone have any idea what exactly is happening and what I should do to fix it?
