Daniel,

I'm not very used to LASTKEY().

AFAIK LASTKEY() gives you the last key pressed on a single contol - even if it is days old.
From the help:
LASTKEY( ) is updated when you move between controls.

I do not understand why you check LASTKEY in the Mouse* event. If somebody press the right mousebutton the menu should appear as usual independing on last keystroke. Or does it interfere with the menu?

I personally would not use LASTKEY, INKEY and the like in an OOP environment. If I need to check for keystrokes I would use Keypress and KeyDown events to check for keys pressed. I would store the result to a property and read it in methods / events that need the information.
