tis morning I installed the lastest version (beta) of display fusion.
Result the system is very slow everything seems repond as if was sleepy especially Firefox, this extremely slow - pages are loaded in serveral minutes instead of seconds
as soon as I quit DF everything imediately (!!) works like charm, tabs in FF are responsive .. tabs popup directly
also M-Edge is sloggy but not that much as FF.
I had this issue with a slow system before !
