windows 10 cursor disappears when mouse unplugged

What they ended up doing was plugging in a wireless USB mouse receiver (without actually connecting a mouse). It seems they weren't able to find a software solution. I've looked around and found a few other people with similar issues. Apparently there is an option to enable the cursor to appear where the screen is touched in the 'Pen and Touch' section of control panel, but I obviously don't have that section since I'm using a desktop. Presumably, this is done to accommodate touch input. So, whenever Windows 8 detects that the USB mouse is unplugged, it removes the cursor from the display. I am able to move the invisible cursor and click and interact as if the cursor was there, but the actual cursor graphic isn't shown. Unfortunately, the cursor is completely invisible in Windows 8. I am able to move the cursor from my Mac Mini (on Monitor 2) towards Windows 8 (on Monitor 1) and share mouse reacts appropriately (it displays transition animations and transfers keyboard/mouse focus onto the Windows 8 desktop). My problem is that whenever I switch the KVM from Setting 1 to Setting 2, the mouse cursor disappears from my Windows 8 desktop. To accomplish this I am using ShareMouse.

When using setting 2, I want to be able to share my mouse and keyboard between both my Windows 8 Desktop and Mac Mini.

The KVM has two settings: Setting 1 Monitor 1 -> Windows 8 desktop I have a Windows 8 desktop, Mac Mini, two monitors, and a KVM.
