Word, Excel, and PowerPoint intermittently show tabs even though they are included in the "Block applications" setting. The "Only allow specified applications to be in a Group" is not checked.
In the Registry under Groupy>Groupy.ini>Groupy>AddTab
winword.exe; excel.exe; and powerpnt.exe all have the Value=1
In the Registry under Groupy>Groupy.ini>Groupy>AlwaysShowTabs
winword.exe; excel.exe; and powerpnt.exe all have the Value=1
Should these apps even be in these registry locations; or should they have a different Value=?
I believe that those are placed there by selecting this option on install:

(Note: This option only shows on a "clean/first" install, it will not show if you just uninstall/reinstall)
You can force Groupy2 to seem like a brand new install, thus giving you that option to set to No by changing this reg entry to 0:
Computer\HKEY_CURRENT_USER\Software\Stardock\Groupy\Groupy.ini\Groupy\SetupDefaultRules
This should fix that conflict
