I don't know why when pointing the mouse over VMware window Num Lock goes off. Then it goes on when moving it back to the real desktop. Is there any way to stop that. It's annoying.
Yes. Turn Num Lock on in the VM and that problem will stop
You can't disable that small window, but you can set Num Lock state to be the same on the VM and your host. Then, no notification will occur when switching VM and host.
For instance, my Num Lock is On because I often use numerical keyboard.
Explanation: when using VM, there are three different Num Lock states: one from VM BIOS, one from VM OS and one from the host. VM Windows remembers last Num Lock state.
VM BIOS: Main / Keyboard Configuration:
Behavior: for example, if you set BIOS default state to ON, and last state in Windows was ON, when VM is booting, Num Lock is changing from ON to OFF when Windows starts, and then to ON again when Windows finishes booting.
