Neil, I uninstalled, rebooted and reinstalled. No joy.
Basj, here's the info you requested:
1. Windows 11, Version 23H2, Build 22631.3235
2. Groupy version 2.12
3. I clicked the Groupy icon of the group I wanted to pin and chose Group/Pin Group to Taskbar. Nothing appears on the taskbar as a result.
4. I do not have Stardock's Start11v2 installed
Thanks for your help, guys.
Kevin
