Hi there, I have a bug report.
First off, I'm not even sure if this is fixable, due to the way Windows permissions work. I have also searched the forum but not seen this specific issue mentioned.
I use groupy on the job and love it. We are in a "No local admins" organization, and as a result we make heavy use of Windows "Run as a different user" option to run certain admin tools as a different, higher privileged account. Basically this option has windows create another user profile under C:\Users and runs the selected program as that user.
Groupy seems to have a hard time with this, when grouping programs run as a standard account and as an admin account. For example, this morning I have Sublime text, A chrome window with Google chat, Active Directory, and SCCM grouped together. AD and SCCM are run as my admin account, and Sublime and Gchat are under my standard account. Here's the result:

Notice the cutting off of the Windows action bar? This is a telltale sign that this issue has occurred. When I see this, all of the other tabs are non-selectable. Now, I can go to the Windows task bar and change tabs, but that kind of defeats the purpose of Groupy all together. Also, if I click the 'x' to close the tab, all tabs disappear. I can't alt + tab to them, and they seem to be closed....but they aren't as I can still see them running in the task manager and they won't launch until I kill the processes. Weird.
I have also seen this same issue happen in two other variants, which I unfortunately cannot seem to reproduce this morning.
- The first one is nearly the same as this, with the tabs being non-selectable, except the tabs each have all the tab title text overlayed on top of each other, making a jumbled mess of text. For instance, the above setup would display each tab still, but the first one would say untitled (Repos) - Sublime..., then overlayed on top of that SysAdmin Team - Chat ..., then overlayed on top of that....
- The second variant is that all tabs except the one that is selected disappear. The tabs come back after selecting an open program from the Windows task bar. I did have this happen this morning, but failed to grab a screenshot.
Interestingly, SCCM in the above setup does not cause the issue, even though it is running under my admin account. Since it is a newer, actively developed app, I'm thinking this has something to do with running some of the older Windows admin tools on Win10? The AD tool I am running is from the RSAT Active Directory install, which is installed as an optional feature now since 1809. I believe it's from the Win 7 days, and as a result probably runs on a different framework. There is a newer app for AD which I can (begrudgingly) use, but MS hasn't yet developed replacements for all of the other tools I use on a daily basis (Print management, Group policy, etc).
Any ideas?
