I've been having an issue (started using Groupy a few weeks ago) where selecting windows by title bar or clicking within the window does not bring forward that window when I have a grouped "super window." I end up having to minimize the Groupy group.
I've had to turn off Groupy for this behavior to abate.
I am using the most current version on Windows 10 along with Windowblinds, most current version (I keep them on auto update). I have two monitors running on the mobo video (Radeon), DVI and HDMI.
