You were indeed told, by the lead Groupy developer, in this very thread...
Quoting Neil Banfield,
reply 21
The issue was addressed for Groupy 2 users in 2.15 beta.
Groupy 1 had an update 1.51 with changes for this BUT not all the changes can be included due to differences in design. I would recommend you uninstall Groupy 1.51, REBOOT and reinstall as it may be files were not replaced correctly.
The only thing that I have to blame myself for is that I have overread reply #21. It was timewise very close to #22, so I only saw #22, but this is no excuse. Sorry for that.
Several comments have been made since that and two releases, one for each product version...
The comments have not been "made", I needed to "pull" them each time and ask every few weeks to get an update. Morevoer, before posting reply #20, I installed 1.51 (through the app itself, as I cannot find a download on the website for Groupy 1 anymore), tested and the issue persisted. Only afterwards I posted #20. From where should I know that I have to uninstall Groupy 1.5, reboot and then install Groupy 1.51? So blaming me for not installing and testing is not justified from my point of view. I am just upset that I have been asked to install Groupy 2 for testing, while at that time Groupy 2 was not capable of the New MS Teams window grouping either.
In order to solve my issue, which is still not solved by the way...Could you please upload somewhere the Groupy 1.51 exe file, so I can uninstall Groupy 1.5, reboot and install directly 1.51 (which according to Neil Banfield might solve my issue)? Otherwise I will have to install 1.5 and then let the app upgrade to 1.51, which might not be the solution according to Neil Banfield again.
Thanks,
