Having a little problem with my Open Window button

It is stuck or something because i have to press it a little hard in order for it to function. It is the only button that has this problems. what can i do guys? thanks everyone.

get a new mpc...

Ya i don't think i am getting a new mpc just over one stuck button.

open the case, carefuly remove the plastic button, spray a little contact spray into the tact switch (use a bit of cloth around it so that the spray doesnt go everywhere) press the tact switch repetedly to work the spray in, repeat if needed. In most cases this will clear it up, if not youll need to buy a replacent tact switch.
