Is it possible to work with other programs or Chrome tabs when Linked Helper is running?
Then run Linked Helper in it, but do not minimise (not collapse) the window.
After that you can switch to other Chrome windows or programs, which can overlay Chrome window with Linked Helper.
If you have several virtual spaces and Chrome with LinkedIn is in inactive virtual screen, LinkedIn freezes page loading.
So to work with other programs simultaneously, please, keep them in the same virtual screen and disable screensaver.
