problem with doubleclick in gnome 2.4

["Birgir Sigurjonsson" <birgir sigurjonsson roxar com>]

Hei,I am having problems with double-clicking wiht left mouse button 
(Button2).
I am using the example code that is found in the Motif  programming manual.

I am using RedHat 8.0 and RHEL 3.0, Xfree86 4.2, OpenMotif 2.2 and Gnome 2.0

I compile with the follwoing line.

> gcc mc.c -o mc -L/usr/X11R6/lib -lXm -lX11

What can I configure to make the follwong code recognize the double click.

Best regards

** button clicks set a timer to expire on that interval and call the
