Anyone using macros out there?

At a volunteer organisation they have Office 2007, 210 and from what I think is 2003 on different machines.
Recent (10:17 am GMT) updates rendered all command buttons inopperative. Nice one Micro$oft. The tame network gurus here rolled-back one machine and BINGO - it all works ..................
until some neat and tidy mind thinks to switch off the machine or click on a Micro$oft directive to improve the machinr - HA!

Two programmers on different programs have this on their spreadsheets.
Given that there is only one type of button you can put on a sheet and it can be rendered useless I don't see any solution/workaround that is acceptable to give it to a naive user.

Any other texhies seen this yet?
