Yes, I tried different resolution, switch screens, unplug the second screen, run Altium maximized, minimized, open it in little window if Properties isn't opened behind the Altium window.
It seems to Properties do not open at all.

This happens only for Component.
Ports, Lines, anything else works allright.
// I also tried to set everywhere default settings. I am afraid that I will have to reinstall Altium, perhaps I should try newer version if I don't solve this in reasonable time.
