Very strange problem with input events

[Cedric Sodhi]

Unfortunally, I lack a better or just more precise description of my
problem. I get strange behaviour all throughout X, everywhere clicks are
involved.

One thing I think I had already mentioned is that my touchscreen, which
runs evdev does work properly everywhere, but there are no regular
events generated - only XI events.

Also, many applications strangely misbehave in a way that other people
cannot possibly reproduce. Unrelated to the touchscreen, that is. Using
an ordinary mouse with evdev.

Two examples:

Tint2 (the panel) had me "drag" window-icons ("tasks") on the taskbar,
when I clicked them, as if I had held the mouse button down. I was able
to "fix" that by a minor change in the code of tint2, but as no one else
is getting any such behaviour I assume I did not really fix the bug but
only found some solution to somewhich, which fails elsewhere. I was not
able to track the logic which is supposed to run, though.

Second example, Midori (the browser). When I right click a hyperlink and
subsequently left click an entry in the context menu, the context menu
disappears (as it should) and I'm suddenly "dragging" the link upon
which I clicked.

Similar things happen everywhere else, too.

I'm not even sure where to start looking. I wish I could get a
suggestion from you, what to do.

thank you,
regards,
Cedric
