pen on Aiptek tablet became oversensitive

[katties]

However it sounds, my pen that comes with Aiptek 600U suddenly became 'oversensitive' and reacts double, i.e. literally 1 click works like a double click. I checked mouse in the same settings and it works normally. I checked also 'mouse' in 'preferences', but everything seems to be normal.
By the way, it happened after I reinstalled Aiptek (it stopped working after Adobe update).
I'm not pro so I run out of ideas what to check. Could someone help me, please.

I'd start by removing any trace of the tablet and starting again. If that doesn't work, try to find older copies of the software, maybe the newest software you installed has problems.
