oh i see.. looks like Wacom has trouble too. Equipped with Wacom Feel stylus technology and software.. this is opera link
but i dunno if it helps.. also if ya could change levels of pressure sensitivity nevermind that won't help either..
maybe opera devolopers will work on those modeles like yours and the Wacoms.. (am sorry tho..
this extension is for stylus
if ya think it could help in some way..
