<html> Greetings, I am attempting to use PSD 1.2.1 with GNU Emacs 21.1 and MzScheme 103 under Windows 2000.  When attempt to use it I get: The ^U Esc ^X works but when I try to add a break point with ^X Space I get: Wrong type argument: sequencep, 6 in the Emacs mini-buffer.  The "6" seems to correspond to the line number I am attempting to break.  Of course I have the cursor in the source file when I attempt the ^X Space. I appreciate any help you can offer. --blake </html>
