You have to set the area for dragging (second option from the bottom) to the highest value (20 pixels) and the starting time for dragging (third option from the bottom) to the second lowest value (100 msec), and now it seems to work for me. I am sure that I tried those settings back in April and they did not work then, so maybe something in KDE has changed over time. Anyway, I'll get back to this topic later and tell you whether I could reproduce the misbehavior in my daily usage or whether this is really solved.
]]>Maybe there's a problem with that setting in Qt4? I consider this to be quite a serious accessibility issue, but it doesn't effect me in this particular case since I don't use KDE4.
]]>Frustrating, maybe if I have time for that I'll test other DEs/WMs to see if it is really KDE related, at least thats how it appears to me.
edit:
Maybe I should paste my xorg-settings for you to see

I only included the stylus since it is only that which concerns me so much.
]]>The keepshape option did not work correctly for me, drawing a circle on the tablet resulted in an oval on the screen.
]]>Oh, and by the way, you don't need to do the TopX/Y etc. stuff to get your 4:3 tablet to match your 16:10 monitor. There is actually a simple option called keepshape which does that for you.
So just add: Option "Keepshape" "On" and your fine.

I really think this is rather a KDE4 or QT problem, since in Firefox I never experience these accidental drag and drops and as I said before, in Gnome/Ubuntu it also never happened. Weird.
]]>Although 10 might be a little to much I don't notice any hinderance in my daily work with that value. I think this can also be changed with wacomcpl under stylus->feel->suppress points.
]]>I tried to modify the setting for dragging and droping in the system settings, time and area for dragging, but even though I reduced it to minimum (not zero though, I would guess dragging wouldn't work anymore then, haven't ried it out), I still get these accidental drag and drops.
So my question is, am I the only one who experiences this annoying behavior in KDE4 and if not, is there anything I can do about it?
