I created a bunch of tabs with just Explorer and grouped them together under name "explorer".  Closed the group, later tried to restore group.  Just get a bunch of errors as if Groupy thinks these are applications instead of paths controlled by explorer.exe process.  One of these errors for each tab:

<path>

This file does not have an app associated with it for performing this action.  Please install an app or, if one is already installed, an association in the Default Apps Settings  page.

The groupy logic does all specify that the OwnerProcess is explorer.... they all look like this:

[GroupyEntry1]

OwnerProcess=C:\Windows\explorer.exe

RunElevated=1

Target="C:\bin\gw2_taco"

MatchingClass=CabinetWClass

Not sure what's  going wrong.

thanks,
