Yes, that's one of the reasons I thought 'his tablet is not sending
core events -- or, it's only sending core events occasionally'. The
same thing happened to me when stylus wasn't sending core events -- it
worked in other programs such as Inkscape, only partially in GIMP. As
soon as I made it send core events, it worked fully in GIMP.

Okay. Thanks for satisfying my curiosity. I'm as baffled as you, at
this point :)
