KVM Switch seems to misbehave in kde.

Question

When using the kvm switch to swap between PC's when i come back to Arch all my shortcuts go haywire. Capslock reverses its self, so caps lock on means cap locks off, shift letter acts like ctrl letter i.e trying to type in a message box in konqueror shift t gives me a new tab. Bash behaves strange it gives me ctrl letters again, i.e typing s I get (i-search). Scroll wheel will zoom in/out fonts in konqueror rather than the default scroll up/down.
Following links opens a new tab where it would follow the link and open in the same tab. I've run out of ideas I tried re-installing all of kdebase, I tried both kernels, now I'm stuck I can't see anything in the logs. Any ideas much appreciated.
It can be cured by typing reset in console, sometimes I need ctrl j a couple of times.
This is kdemod 3.5.7-18 with either the latest ck kernel or the default Arch one.
My apologies if someone thinks this belongs somewhere else please move it.

Garlics not working, but think that's all I'm left with.
After posting last night out of curiosity I un-installed kdemod installed kde proper rolled back a kernel still the same. I'm pretty sure its unrelated to kde or the kernel now so I suspect its the kvm. I've got nothing bound to ctrl ctrl.
What I find strange is the recovery, why does ctrl j several times or sometimes in a new konsole window followed with reset work, why would this affect my kvm or the way its being interpreted?
Now to try a new user Fingers crossed this works but I got a feeling this won't be the case afterwards I'll try another usb port. After that as I've not got another keyboard(Though I'm 100% input devices are fine as the other OS isn't showing any strange symptoms)  I'll swap the ends of the kvm and see if I can make it happen on the other OS.
Dmesg is empty I get no mentions when it happens, I monitored it whilst doing it and prowled all the logs just to make sure.
I'll post back if there is a solution but I think one side of the kvm is on its way out perhaps.
