I see nothing wrong with that - evidently keypress is something 
different than {"H", "E", "L", "P"}, but since you don't show what it is 
(or how you compose it), there isn't enough information to say anything.

Try inserting a "pipmak.print(execute)" to see what's there, or if 
keypress is a global variable, you can examine it using the Lua command 
line (enter "keypress" and press return, then use the crosshairs on the 
result to open the table inspector). (Unfortunately 
"pipmak.print(keypress)" isn't helpful, as it doesn't print the contents 
of the table.)

By the way, you don't need to "screen:setimage(preScreen)" twice, once 
is sufficient - it's still the same image even after you draw into it.
