[Fluxus] keys-down

[gabor papp]

i found that (keys-down) sometimes works in a strange way. it returns 
mouse button presses as 0's. and i also experienced that some keypresses 
get stuck in the list and remain there forever. i'm not sure how it 
happens or how to reproduce it, but i see )'s and ('s getting stuck 
quite often, but alphanumeric characters behave this way as well. has 
anyone experienced this?
