Hi there, a fan of yours since many years and I am still in love with your software (impossible to understand why Apple didn’t ever do something like you’re doing built in OS X - why, not too bad for you :)).
After the last update (or maybe the previous one) Total Spaces 2 behaviour has started to be a little bit bugged.
Total Spaces 2: latest version
OS X: 10.11.6 (15G20015) El Captain
When I swipe (4 fingers my choice since the beginning and it always worked) it usually changed only the space on the monitor where I was (swiping). Now, and it’s SO frustrating that maybe I will have to disable it until it’s solved, it changes space on my external monitor AND on my MacBook Pro at the same time.
I tried to find something that address this specific issue and couldn’t find it in your Forum. So, here I am, hoping that you can take care and solve this issue asap, because it’s really screwing a person workflow when accustomed to work with both monitors.
