Yes. Call R_Process_events() periodically.  That will clear the Windows
event queue.

Just in case it is catching you, the output in the console is always
batched up waiting for the prompt. Use ^W to toggle this.  My guess is
that this _is_ catching you.  Do send complete lines (with \n) via
Rprintf if possible.
