I've been reading peoples posts about this problem with the
'asfunction' command and it seems that no one has a solution for
this! The one where you call the asfunction and then clicking on a
button without moving the mouse doesn't work after the first press.
I am stumped on this myself when i came across the error, but
what I did learn which might help someone in finding a fix is that
using the FLVPlayback component, if you click on one of the player
control buttons then click any normal button the problem
disappears. I tried to look at the code for this component but its
self-enclosed, so I am not sure how it fixes it.
