Well, I just tried your code in 3.2.4 on Fedora 13 and it ran through
the loop, printing
TEST_2
 TEST_0
 TEST_1
when I typed a character (and just TEST_2 and TEST_1 when clicked).
Do you change focus to the image window when you do your 
typing/clicking? What OS are you using?

These errors are from ginput(), which calls

stream = get (f, "__plot_stream__");
...
fprintf(stream....

and the property __plot_stream__ has multiple values. I think this 
should be changed to

stream = get (f, "__plot_stream__")(1);
