I am getting this in seemingly random documents. This has happened to a custom template I created many months ago called "Notes.dot" (.dotx?) and also in "Normal.dot", the default template.
The only thing I've been able to find online is that if you have a malicious addin it could be doing something. Problem is, I haven't installed any add-ins. And I've just now tested by disabling all default add-ins (even though the 4 that were active didn't look suspicious).
Some documents it gives me the prompt, other times it doesn't. It's just really ugly. As a temporary solution I've made this AutoHotKey code:
#IfWinActive, ahk_class OpusApp
~^s::
WinWait,,Do you also want to save changes to the document template?, 5
If !ErrorLevel
ControlClick, Button2,,Do you also want to save changes to the document template?
return
It's terrible that I had to use a third party application like that. I hope there is a better solution.
Despite saying No to saving the template, I keep getting prompted. If I wanted to save the Template, I'd manually save a template. And from other research online it seems this pop-up is impossible to disable. Everyone frets that you'd get accidental changes - why is it not an option to deny making changes to templates unless you explicitly wanted to create a template?
Does anyone have any idea what other possibilities there are to add-ins doing this? Is there actually something I thought would not change a template, like selecting a bullet (because using *+Tab and -+Tab together in the same document just leads to problems...) that is being registered as a template change? Clearing a style from pasted text maybe?
