I have a problem with the DMC-touch screen driver. Almost everything is
working fine except clicking a button. I think the reason is that XFree86
doesn�t get a ButtonRelease event after releasing the button (touch screen).
I conclude this from the events that occur.
Example nr1:
If I push a button, the button keeps pushed-down until I push on another
location. Normally with a mouse you push the left mouse button and if you
don�t release the left mouse button, the button on the screen will be pushed
down. If you release the left mouse button,
Example nr2:
If I want to drag a window I push and hold the window and drag it over the
screen. When I release the window (I stop pushing the touch screen) I can move
the window by using a mouse without touching any buttons from the mouse.
I think XFree86 didn�t get a ButtonRelease event because it is still reacting
like someone pushed and hold the left button to drag a window. Physically
nobody is touching the buttons from the mouse or touching the touch screen.
Congiguration:
XFree86 4.3.0 glibc21

I appreciate any help on this subject
