Left mouse click stops working in hyper-v after a minute

Solution 1:

Here's a workaround that appears to resolve the symptom but not the cause. Be sure that your vmconnect window is not in full screen mode. You will then see the menu bar at the top. Under the "view" tab, be sure that the "Toolbar" option is checked. Now you will see a toolbar below the menubar. Click the pause button and then click the play button on the toolbar. You should get your left mouse click back and you can go back to full screen mode. You can repeat this each time you lose the left mouse button.
