KBT Pure - spacebar becomes unresponsive

[xcelerate]

So i got my kbt pure keyboard in, and on a reboot everything works fine but shortly thereafter my spacebar seems to become nonresponsive.
It works  fine in windows at first and i'm happily typing away, i can activate the sw0, 1, 2 and 3 functions with no issues but then about 4 -5 minutes in mid typing the spacebar just appears to stop working, the only way i can seem to get it back is restarting windows/ unplugging the usb cable/plugging it back in. All the other buttons work fine.

Has anyone else experienced this or are there any suggestions as to what could be causing it?

I'm on windows 7 and 8 rtm for what it's its worth, but i i've tested on both with the same result.

Did you try different ports and different computers?

I've been using mine solid for a couple of months without any problems. Have you tried opening/cleaning the switch?

Yes to both, using mxred switches, i will try opening up the switch tonight, and let you know how it goes.

I've been using mine solid for a couple of months without any problems. Have you tried opening/cleaning the switch?

So you've never lost functionality of the spacebar whatsoever, no matter what combination of software switches you use?

Nope, the only ones I use are the disable winkey, sticky FN keys and arrow lock but I've never had any problems.

Still no go on the board, the spacebar works for a time and then just stops working, even though all the other buttons work fine. Unplugging the board/swapping USB ports makes no difference, all the other buttons keep working but the spacebar stays dead. I will talk to the seller and see what gives, i just bought it as well, this has been an issue since day one with it i thought it was something to do with the sticky function key through sw3 at first but it looks like a bigger issue, a bit of a pissoff to be honest.

My quickfire storm is chugging along just fine in the meantime as a workaround.
