TotalSpaces2 has worked well with every app I have tested except for Safari. Looking into it and Apple says Safari may have issues with some unsupported 3rd party apps with Safari quitting, running slowly or other unexpected issues. This would be unexpected.
Safari loses it’s top menu entirely with no way to adjust preferences Safari becomes unusable unless TotalSpaces is quit.
I purchased TotalSpaces to improve my speed, but for browser testing I need to be able to have Safari and Chrome running at the same time and TotalSpaces making Safari useless makes TotalSpaces useless.
