Thanks for the update Angela Robertson, in one sense I'm glad it wasn't me just missing something obvious... but on the other hand, rolling back a recently implemented change in default behaviour without at least announcing the rollback is about to happen is very poor product management. I appreciate your apology, but it really should not have been necessary in the first place, it's not like Microsoft are new to this.
We've been scrambling to obtain a digital certificate for signing our VBA projects since I first became aware of the impending update in mid-June... then immediately after we've incurred that expense and got things working again in the least inconvenient way for our customers, Microsoft just flip a switch without telling anybody? You've got us jumping from one foot to the next and having to second guess what the next volte face is going to be.
