Groupy Application groupings stalls after opening 2 or more than 2 pdf files in Adobe Acrobat.
(Grouping of 1 pdf file with other files is Ok, by it stalls if 2 or more pdf files are opened)
This happens only with pdf files. Not for any other file types or software files (eg word excel explorer etc).
Groupy can start working only after stopping and restarting groupy.
Pls advise solution to above.
