[ltk-user] Problems with double floats

Hi, maybe I'm missing something obvious, but LTK doesn't seem to work with double-floats for me. For instance: (with-ltk () (let ((c (make-canvas nil))) (pack c) (create-line c '(0 0 100 100)))) vs. (with-ltk () (let ((c (make-canvas nil))) (pack c) (create-line c '(0 0 100 100d0)))) In the first case, a window pops up with the line drawn as desired. But in the second case, an /empty/ window pops up. Further, when trying to to close the window, the window exits on one hand, but the Slime REPL doesn't get back. (I have to interrupt via `C-c C-c', and then type `q' to get out of SLDB.) Huh? :-), -T.
