Here's a patch that fixes the problem for me. none

Description Tim Waugh 2000-10-15 20:36:35 UTC 
When running vncviewer from an icon on the desktop, sometimes
authentication is refused even though the correct password is entered into
the dialog box.

This seems to be because of constructs such as this:

password = XtNewString(XawDialogGetValueString(dialog));

XawDialogGetValueString frees and reallocates a value to return each time,
and XtNewString is a macro which uses its argument many times, and so if
XawDialogGVS returns a different value on successful calls during the
execution of the expansion of the XtNewString macro, "odd" things happen,
and password ends up pointing to the wrong place.

Thanks, fixed. (Btw: Why don't you just take the vnc package? You're doing much more with it than I am.)

Ahem.. I thought I had..
Comment 4 Tim Waugh 2000-10-16 10:23:52 UTC 
Incidentally, for those that want to check that it really does fix the problem
for them, the fixed package is vnc-3.3.3r1-10.
