Cost of Progress
Microsoft release a major change and it breaks some old VBA. What do you expect?
The problem here is far too many businesses (my employer included) rely on hacked together VBA solutions for stuff that's mission critical. Either you take on board the responsibility that VBA entails - i.e. you accept there may be migration issues and upgrade Office accordingly; or you're leading your business down the garden path. Any good developer will consider future migraiton when they choose a technology in the first place.
On the opposite side of the coin - my word and excel files open fine thanks. I can't find half the functionality though. THAT is the biggest migration problem businesses (should) face.
Paris, because maybe she can use the office ribbons.
