There is an issue whenever I right click a guide link to open it in a new window which happens to me many times when I use Manager, it renders Manager not responding and I have to launch “activity monitor” on my Mac the equivalent to “task manager” in windows and I have to force quit = end task and relaunch manager.
I can duplicate this behavior and will put this into the bugs category.
Meanwhile, @a_marhoon91, do not right-click. Left click, and your browser will open (if not open) or create a new tab, and you will be taken to the Guide.
I’m already lift-clicking since I’ve been encountered with this issue.
Fixed in the latest version (19.5.4). This version also bumps requirements for Mac OS X. Manager requires now version 10.9 or higher (previously it was 10.7 or higher).
