Thanks for the response and great questions.
1. I am using what's often dubbed the 'offical' 7" screen. here is a link to the manufacturer:
2. Sorry for the confusion on the bar. I am using the tool bar. And to be specific, trying to hit the configuration buttons (wrench) etc. minimizing, closing etc. all work
as normal, and the touchscreen works for normal rpi menu navigation
As an aside, there is a fair amount on other forums
for this issue. The link below acutally has a video demonstration:
No touch on official 7" Touchdisplay
There are also several threads on this forum which overlap with this topic. Just search on touchscreen and they all seem to circulate around the same issue.
Thanks in advance for the assistance.
