Where to start....???? SO many things are messed up in Office 2007. Here are my top 3: #1: Word/Excel/PPt: The ribbon interface changes things around so drastically that doing what was once simple things in Office XP/2003 is now a frustrating exercise in lost time and productivity. #2: Excel: First, MS has a hotfix (a 32 MB download) for a math error (yes a math error). Very few users will ever be likely to hit that value range on a calculated result, but still unacceptable for a mainstream number crunching program. But if you are one of those unfortunates, and the error ocurrs in a very large, complex spreadsheet, then the error could cost a business a fortune if it's not caught. #3: Excel crashes if you try to specify a custom value range for chart error bars by selecting the appropriate row/columns from the worksheet (like you can in previous versions)... you have to enter them manually by typing the arcane "=Sheet1!$A$1:$Z$1". Even if you try to click over to the worksheet while the entry box is open Excel will crash and you lose everything since the last Save. This bug is probably lurking in other areas as many functions make the same calls to a common software modules where the bug really is located.
There are many other bugs in this product too numerous to list here (goto the MS Discussion Groups on Office 2007 for more).
