That was indeed the case. The updated code passed the wrong
initial-bindings to the event handler thread, which caused some streams
to be bound to background-streams in your application, in turn causing
the force-output calls to fail.

The attached patch should restore functionality of force-output in your
application again. Also, I re-ordered a few definitions in order to
eliminate warnings at compile time.

As always, compile and load the patch file to use it.

As noted in my previous mail, I'll need a bit more time to work on the
output issue and Japanese text in text fields.

Good luck,
