in process of writing a prog at some point the keypressed function wether
as own procedure or as bool in the draw() method would not aknwoledge any
keystrokes. when playing around with the code, i found that even changing
or removing remarks would affect the behaviour of this. happened with the
0135beta, not testet as embedded in html.

here's the code which doesnt work, however changing some lines within the
big remarkblock at the end will sometimes enable keystrokes again. also, if
they don't work, sometimes that happens after the 2nd compilation or
execution of the prog.
please forgive me if im temporarily stoopid or something. found nothing in
the other bug sections so far.

my guess is that your code is using up a lot of cycles, and not giving any
time for draw() to run, so the "if (keyPressed)" code doesn't actually have
a chance to go.

no response, closing bug.
