My mac has been a fine performer until I started running out of space on my hard drive. I have a 15" macbook pro, with the latest Lion updates. HD is 200 GB, 4GB RAM. I took time recently to move all large, non-daily files to my external HD (which I leave at home). Most of those were movies that I had made for work. I use MS Word for Mac to make a newsletter for work. This has been working fine; however, today I'm getting boxes saying that Word doesn't have enough memory. Is the fact that I have 89GB left on my HD making this a problem? I figure I've got 4GB of RAM and I'm only using Word (not a ton of other apps at the same time). I don't understand what could be the problem. Please help!
