Error messages in OS modal dialog boxes are not helpful, they frequency contain so much info they don't fit in the window, can't be copied, and you can get repeated windows popping up over and over and over ...
I would rather see just a single list of all errors at the end of the operation displayed in the Unity console log
I need more specifics to understand this.
Could you provide a screenshot of a few of these popups so I know where they are coming from?
Please email to support@perforce.com and I'll open a support case for you.

Thanks Norman, I've opened a support case with some screenshots.
