In one application I've implemented an up/down/left/right navigation by handling "ALT + Cursor" keys. Surprisingly in the IDE the TForm.OnCreate and TForm.OnShow events fire while using this key combinations; mostly on "ALT + LEFT" and "ALT + RIGHT". Is this "application restart" intended?

That sounds like an alternative for the "Back" button in the browser. Could that be what is happening?

(I've just tried to use the Ctrl-S, Ctrl-P for things myself, only to find the browser makes things awkward with save and print! The only keys I have found that are safe are F8 and F9, and using a prefix like \ followed by another character. (This is in an application with edit boxes for ordinary typing)).

It's not intended, but they're definitely IE shortcuts:

I'll see if I can get the embedded browser to ignore them and pass them on to the application.
