Same thing here... Wondering if the button is pressing down the actual switch on the board or is it a separate switch wired to the respective board? Aside from that, too many users reporting the same issue, may be a design flaw.
Also, sending it back to VS is not really an option for me, being in Europe makes it too expensive and time consuming, so if anyone finds a DYI fix to this, would be great!
Being in China theres a good chance my VS will get lost in translation as well. Seems to be a design flaw. I'll see what I can do during my next visit stateside.
