[plt-scheme] tracking user input boxes in drscheme

In my DrScheme program, I seem to have accidently written something
somewhere that asks for user input, Which occurs as a white box with a black
border and a "eof" button that keeps poping up in the interactions window.
Is there any way to track where this is comming from?  (I use "read"
throught the program, I did a simple text search, and I saw none that ask
for user input, they all read from string-ports, or "process" calls, etc.)
