Hi Petr,First of all, congralutations for your software.  I would like to suggest you  a little bug, not an real issue :I've installed the 1.8.1 version on my little Asus EEE PC1000 computer with Linux Mint 17 distro. The screen resolution is 1024x600 max...The preferences windows seems to be fixed and not resizable so the OK button and Cancel are not reachable....Can you fix it ?Thanks and regards
