strange 2.0 bug

[allenb@cs.uoregon.edu]

I am using 2.0b1 and have a strange problem.  I have a function
that draws to a color window.  If I place a print statement in my
loop the program will not draw.  If I take the print statement out
it will draw.  If I use a format statement it will draw but it 
spools the output and prints when the drawing is done.  Also
Command-. will not abort the loop and READ will not wait for input.
Are there any fixes for these?
