What is the problem?
Prior to upgrading to 1.4.1 (and 1.4.2) on my 7" RPi screen, using TouchUI I selected shutdown and then I got the dialog up and confimed by pressing the "proceed" button. Since 1.4.1 upgrade the Proceed/Cancel options are hidden off the bottom on the screen so I cannot shut down locally, but have to go to a PC on my home network to shutdown from a browser. I presume it is not not detecting or resizing the dialog successfully?
What did you already try to solve it?
Upgrading to 1.4.2 did not resolve the issue. Running updates on the RPi (sudo apt-get update and upgrade) also did not help or change the issue.
