I just received a few bug reports from different clients stating that
very basic functionality of an add-in I am writing does not work. So
I tested it gain, and sure enough it no longer works for me either!
It certainly used to work.

So I'm guessing that an automatic update from Microsoft has corrupted
my and my clients machines. Most annoying. My Addin does not use any
system software or interfaces. Just plain VBA. And very hard to know
what is going on unless you really lock down windows update.

Anyone else had similar problems? First time that it has happened to
me in 10 years.
