No touch on official 7" Touchdisplay

[verkerkbr]

Hallo,

i have the problem, that i can not use the touchscreen to control OpenCpn. To control the "normal" raspbbery pi system the touchscreen works fine. Only in the OpenCpn program i can not use it.
When i tap on the menue items in OpenCpn nothing happens. With an external mouse everything works fine.
I tried to install OpenCpn on an Raspbian installation, all works fine there.

Any idea?

Have you switched on touchscreen in OpenCPN ?

Do you need a calibration of the screen ? Sometimes is your finger not on the right place. But then moving the screen must work.

I have used touchscreens before and they worked. With an usb connection for the touchscreen commands.
