Based on the information provided, it's difficult to say what might be going wrong in your setup. Also, I know this might sound weird but would you please try keeping right-click pressed on your mouse for about 2-3 seconds? I've seen similar behavior to what you describe when using VMs or when using VNC. However, "problem" was "solved" with the long-press of the right-click.
Maybe the information from the workspace log has some useful information for tracking down the issue. Would you please attach that information? You can easily obtain it using Help => MCUXpresso Save Info for Support.
