Cursor Not Visible on Client Machine Without Its Own Mouse

[bonemouth 0]

Hi, I randomly had this issue crop up with Synergy 3 RC2 and updated to RC3, where it persists. Everything was working fine for months until today. I use a KVM switch, and the cursor is invisible for the client machine. If I connect a separate mouse to the client machine, everything works fine. I've read where some people had scroll lock enabled. That wasn't the case here. I also reset Synergy on both computers and restarted them and reset my router, but none of that changed anything.

Please help me fix this so I don't have to have a separate mouse installed on the client!
