[openbox] Shift key misbehaviour in Openbox

[Dave Coventry]

Hi,

I have 2 machines both running Openbox as their window manager.

I have a laptop and a Desktop with multiple monitors.

I run Blender, the 3d modelling program on both (blender3d.org).

This application uses the shift key to make multiple selections.

On the laptop this works as expected, but on the Desktop machine the
shift key modifier disables the click. (Leastways, nothing happens
when a second item is clicked with the primary mouse button)

I have already driven the Blender3D forum mods to distraction trying
to find the cause, but it turns out it works fine under another WM
like KDE.

Any suggestions?

~ Dave.

PS thanks for a great WM, by the way!
