I’m using VMware Horizon Client on a Apple Mac for connecting to Windows desktop at work, and frequently encounter screen freezing of the Horizon Client.

This seems to be triggered by swiping left/right to switch between OS X ‘spaces’ and view a local screen on my Mac.

When I return to the Horizon client window it is unresponsive.  I think it gets confused by switching ‘spaces’

What I find interesting is that mouse clicks seem to still be processed in the background

because when I finally get back to my remote windows desktop, it was updated.. For example clicking to close a window actually closes it in the desktop,

It’s just the Horizon Client does not repaint again. I use a 3 monitor setup and the horizon windows on the other two monitors usually continue to function.

Note:

To recover, I previously restarted the client each time which was painful, but I found an easier workaround by bringing up the menu bar and selecting CTRL-ALT-DEL menu item..

All screens will go dark/ or to the remote Windows screen that asks to lock/change password/etc.., except the frozen one.. but if I swipe left/right again to switch ‘spaces’ (on the frozen screen or maybe on one of the other monitors, i don’t actually remember the exact sequence that works..)   I can usually make it come back to life.. then I just hit ‘ESC’ key for windows to return back to my windows desktop where I left off.  Hope that helps someone.
