Several redundant panels can be opened

Description

Several redundant panels can be opened.

Examples:
Help -> About
Help -> Announcements
Help -> Check for Updates
Tools -> Components Check

Expected behaviour is that if the chosen panel is already open, switch to it rather than opening another one.
