I run a modded "install-clock" shell script, last time I have bricked my iLiad with a bad script version.
Execution rights of /home/root/starth.sh didn't get lost. Uuuh.

I found 1 problem: Because the the clock is added in toolbar, 2 icons in the left disappear.
A screenshot of clock in toolbar is attached.
[EDIT:] Correction: the portrait/landscape icon is missing in pdf viewer; larger/smaller font icons in html/txt viewer are missing ...
