I’m not sure if this is the best place to post this, but I’ve not found it in other posts and wanted to make others aware of my fix/workaround.
I’ve had problems with the desktop being unresponsive to mouse clicks. It took awhile for me to make the connection that it only occurs when Chrome, installed from the Software Boutique, is open. I do not have the problem on my laptop, it has Chromium. Both open the same 4 home tabs at start-up and have the same add-ons.
I installed Chromium with Synaptic and the problem does not occur. With Chromium minimized I open Chrome and the desktop becomes unresponsive to mouse clicks again.
So at this point I have migrated my settings and add-ons to Chromium and uninstalled Chrome.
