Hi Venemo,
thx for the reply. I am very sorry, the desktop-changing is totally random, when it happens it happens usually just after a reboot. I mentioned that because another person experienced it, so something wrong doeas exist somewhere, but I didn't figure out how to reproduce it.
About the installation problem, I simply used HAM and it reported installation faild, but funny thing is that the version currently installed is 0.2.2 beta. I noticed it because the focus is working better now, so checked the about and had the confirmation the upgrade had been done. No apps installed with apt-get commands (as far as I remember - never reflashed since NOV last year). If more details shows up, I'll let you for sure.
Thx for the great app and for your work!
