ok, today is the day I've received my dr1000s back, and guess what, now that 1.5 is working, I have the pen bug too

the device was on the desk, waiting for a couple of hours, and pen did not work. I've turned it on and off using the buttons, and it works now.
if this is the same issue with pthwaite, I'll have to send it back again? that's very frustrating. are there any other users out there having this problem?
Kind regards
Seref
