The icon is embarrassingly childish!

Uses single precision arithmetic.

Titles which contain control sequences are not perfectly centered.
(Improved?)

Repeatedly rapidly clicking on one button can sometimes hang the window
system. (Fixed??)

Input focus is not always restored to the "Robot command" line after a
dialogue window has appeared and disappeared. (This is fixed, but only
by bringing the control window to the front which can sometimes be
annoying).

Changing directory from various places (e.g. "CD" command, file
browser) could be integrated more (ensure everything is updated
correctly at same time).

The future of XView is not good. I need to decide what to replace this
with, if anything. (GNUstep? TK/Tcl?, Wine/MS-Windows?, Motif?).
