Well, I'm slowly starting to move everything over to my new macbook from my desktop Windows XP PC. The latest thing I moved over was my financial stuff. I set up all my accounts on Quicken and put my budgets and hours list onto my USB drive. I was using this with Excel on the WXP and I'm opening them with Microsoft Office for Mac. Here's the problem... On my budget (13 worksheets, 1/period) the cells don't change as I enter numbers. If I save it, everything updates, but I don't like that idea. When I'm doing my school work and with the hours (one worksheet with 52 lines (for the weeks) and a few other formulas) I don't have this problem at all. I have the 2.0GHz Macbook with 512MB of RAM. Could that be the problem? I have no other applications running at the time when working on this. I hope someone can help me, I'd really like to try to get everything moved over to my Macbook. Well, mostly everything. I still like using a full size screen/keyboard/mouse/etc. but want to get used to using a Mac. My next desktop will PROBABLY be an iMac.
