Hello 25F
Yes......directly plugged into PC1
I also suspected the KVM switch. However I have now ruled this out as I was so sure it was the switch, I totally disconnected it. This was OK for 2 days then slowly the problem started to manifest itself again. This was with all cables plugged directly into PC1. KVM switch in its box as I thought it was faulty.
I have swapped all the cables about etc all to no avail. The mouse would appear to be working fine as I do not have any of these problems when using PC.2 ..........with or without KVM.
Odd isn't it
