The child windows don't close itself after hiding PL windows

[BenYeeHua]

The child windows(like "About Process Lasso" and other setting windows) don't close itself after hiding the PL windows, by clicking on the tray icon.
And the Taskbar Icon/Button also missing after hiding PL windows, even the child windows is still there.

And, did this is a feature or a bug?

This is due to their nature, as separate and distinct Windows. They do not block the main window (don't stop it while they are visible), so their behavior should be independent of the main window.

In other words, expect it to stay like that

Ya, so you can hide the big window without closing the setting window.
