What does “switch to installation mode” do? I can’t find a description in the online help nor in the FAQs ???
Using the firewall on Vista Ultimate, all critical updates installed.

Installation mode stops any popups while you are installing a new program. It will then automatically switch back to your normal mode for you or it will popup a window asking you if you want to switch back and you can choose yes there if the install is done.

Thanks 
“Reminder” window must be hardcoded ‘always on top’ imo. I’ve not seen that window about 2 hours after installation (because another was on top) - means ALL activities was learned as ‘installation’?
Good shout.
I have a suggestion: the “switch to installation mode” (or back) should be made a menu item for the tray icon. Having to open the main window to reach it looks like a bit of overkill to me… Just my 2¢
Absolutely yes! 2$
