Not to discourage you, but there are continuously new bugs with all the software (Excel, Word, ...) This is nothing new.
Broken treeview ActiveX controls
Images not displaying
Action queries crashing Access
Properties not being saved
And the list goes on...
This is the reality of today's Microsoft. As fellow MVP Rohn007 puts it:
"Computer Haiku:
Yesterday it worked.
Today it is not working.
Microsoft is like that."
To add to that, Microsoft, like most big corporations, has very poor public communication. We never get any status updates regarding fixes.
They have very recently created the bug and fixes site (link can be found at the url you posted), but even there they don't give any ETAs, so it remains entirely a waiting game.
There is little that anyone can do. That said, you always have the choice to use any number of alternate software applications.
Just know you are not alone, a great many feel your pain!
