I have recently upgraded from 10.3.9 to 10.4.11 I didn't see the option of wiping my harddrive clean with the install (I was expecting this to happen automatically). All of my original programs remain, but my old version of Microsoft Office v. X is having issues (not enough memory to copy and paste in a Word document?!) I have downloaded two updates for Office X from Microsoft.com (10.1.7 and 10.1.8 updates). I also downloaded a security update that wouldn't install because it could not find the correct version of the software. Should I get Office 2008 or reinstall Tiger? Any other advice about upgrading from Panther to Tiger would he appreciated.
