Touchscreen reacts strange

Since a couple of days I notice that my touchscreen is reacting a little strange.
Sometimes when I touch the screen a different part of the screen reacts.
Lets say I want to touch the upper right of my screen , one button on the right reacts

But then after a few seconds everything is working normal.

To see what the problem could be I made my mouse pointer visible and notice that the problem appears when Ik touch the screen gently.
When I press harder then eveything works OK.

I already re installed drivers , but problem is still there.

Screen is stripped down to be attached to a homemade bezel. Now I wonder if the problem could be that the touchscreen is reacting on this. (touching the borders of the bezel

)

Anybody who also had this problem??

Calibration has already been done several times, but this didn't solve anything.

do you have your screen iin your custom bezel or is it in the factory bezel? I read on here if it's screwed down to tight to the bezel it will have a negative affect, also I noticed with my screen when I calibrated it with my finger it would skip around at times, but when I used the stylus to calibrate it wouldn't.

I dont use the factory bezel. Screen is attached with glue to my homemade bezel. Between the bezel and the screen I used a very fine fome , to prevent damage.

Idea is no to loose the screen and glue it back again , to see if this will help.

Also, where are the A/C vents, are they near the screen. I had something similar happen, i would drive with the windows open and have no issues. If I ran the A/C though the touch panel would be jumpy and hop all over the place when touching it..... Then all of a sudden its working like nothing happened.

This is not the issue in my case:

i had a noticably simular problem, after a while it keep progressing till it was un usuable, so i bought a replacment touchscreen from the mp3car store, fixed it back to new. But u said urs is glued in? ....that might be a little tough to replace lol

Maybe the glue is the problem.... It could also be drivers. Have you downloaded the latest?

Dont get me wrong.Touchscreen is attached to the LCD using tape.Then I used some glue (have to make it hot before I can use it) to attache all the screen to the bezel.
The back of the LCD is the only part that is glued to the bezel.

Touchscreen doesnt touch the gleu at all.

Then it probably would be feisable to replace the touchscreen. like i said in my previous post, that fixed me right up.
