One day I was able to drag objects from one screen on my remote PC(Windows 10) to the other screen, then one day I cannot without stopping first. Seems like this happened when I started using the Mac version of LogMeIn client. For example, I can click and drag a Windows Explorer window from one screen to another, but when the window is halfway between the 2 screens it stops, I must 'unclick', drag my mouse pointer to the destination screen and continue to click and drag. Very annoying. Both my Mac and the remote PC are running 2 monitors and I have LogMeIn set to Multi-Monitors.
@MotionMatt If this used to work previously from your Mac client, have you done any troubleshooting such as rebooting or re-installing the Host software itself?
Prior install was the Windows 10 client. Got a Mac, installed the Mac client, then started experiencing this problem, but I can't be certain it started with the Mac. Guess I'll try powering up my old Windows system and see if I still see the problem there. If so I'll try an uninstall/reinstall on the Mac.
I tested this on the Windows 10 version of the client and was able to drag objects from one screen to another smoothly so this would appear to be a flaw in the Mac version of the client.
