Issue with windows key bindings

[Iron Bloke]

I am not sure if this is a RS2 issue or a PC issue, any help will be handy! This issue only happens when playing RS2 or RO2. If i play for an extended peroid of time, my keyboard buttons, instead of contolling the charicter, start opening windows aplications, for example pressing 'm' opens messenger, 's' opens the start bar etc. I've only had this issue with the two games listed. Very annoying, and the only fix i've found is restarting my pc.
thanks in advance for your help!

I notice some gaming keyboards now have a lockout feature for the Windows button, because pretty much all of us press it, from time to time, when playing a fast game that uses W, A, S, D type controls. That is what causes that problem, 9 times out of 10.
