I want to modify lesson 11 that way, that it checks for the alt key being pressed. But if i check: if (keys[VK_ALT]) i get an error message...(VK_DOWN works fine) Thanx SnAkE''s Programming Resources

The correct virtual key constant is VK_MENU.

OK, so far so good...
if i press the right alt-key, my character moves forward, but doesn''t stop when i release the key.
If i use the left one, nothing happens.
(VK_LMENU doesn''t work either)

Thank you, for your help
