When I try to run solver in Excel, it crashes the program. It started happening only occasionally, usually if I tried to run Solver more than once in the same spreadsheet, but now it happens every time. I uninstalled and reinstalled the value pak, installed all updates, and did the disk utility repair, but all to no avail. I've seen this same question pop up pretty frequently in older posts - is there a solution? I've got an ibook G4 running OS X 10.4.11 with Excel 2004.
