Early RRS2 (MY14), owned from new: over the last couple of days the touchscreen has become very temperamental. Yesterday wouldn't work at all; today, after approx. 30 mins and for next two hours, worked sporadically – sometimes no recognition, sometimes button lit up but didn't proceed, sometimes only worked when pressed with two fingers. No consistency on position on screen or type of command.

Has been very cold here (but never had the problem before). Has anyone suffered the same thing? If so, is there a simple "reboot" type solution I can try myself or do I have to accept that it might be the beginning off the end.
