Just so you know, these are failed assertions.. meaning that the assertion
"src != NULL" failed.. sorta means the opposite of what it looks like :)
ie, in this case src == NULL.
My guess would be the pixmap wasn't really in the current directory, or
you got the filename wrong.

Hmm.. which example are you refering to ? I thought I used windows in all
of them. At any rate, a dialog creates a window, and then packs a vbox
and a seperator in it.. it's just a shortcut for creating dialog windows.

You're right.. it shouldn't. Check to be sure the .xpm is in the right
place (in the button example, it's ./info.xpm) and that it's a proper xpm
file.
I just retested the example in section 6.1, and it seems to work fine.. if
I rename info.xpm I get identical errors to what you stated.

Ian
