'alt' button bug under processing 68 and w2k

hiya,
i'm using processing 68 under w2k. there seems to be a bug involving the 'alt' key. hitting the 'alt' key results in a null pointer exception. specifically, when i run the code below, i get the error message which follows. note that to run the code, you'll have to provide your own insertImageHere.jpg in the data directory of the sketch.
