I use Groupy a lot with Chrome and Windows Explorer 5-10 tabs, a lot of files to sort into folders, and Groupy makes my life a lot easier.
However, regularly, it starts to freeze, it lags fors 10's of seconds, and the processor ends up with loads of 25 to 70% by windows explorer, and nothing more can be done. You have to close and relaunch windows explorer.
Without Groupy, I never have these lags or freeze, and even with Groupy installed, if I put it on OFF, there are no lags or freezes.
IF I put it On, it can starts to lag after 10 minutes or 2 hours, so productivity ...
Installed Groupy is 1.49.1, but it was the same with 1.48.
Windows is 10 family 18363
