Problems with 10.10.5 Yosemite and Total Finder 1.7.8

I have been trying the latest Total Finder on the latest Yosemite (10.10.5) and have encountered too many errors to continue with it. Can’t shut down the computer sometimes, can’t move to another program from Finder, or vice versa. Unable to access menus, etc. I have been using Total Finder from the start and will be more than happy to go on using it when these glitches have been sorted out. It’s a great program.
