Actually it was not really me, who changed the response of the mouse 
buttons but it is contained in ETH native Oberon for Windows. As far as I 
understood, Emil Zeller has done - at least part of - the job. In (nearly 
all) Gadget-Modules (for examples BasicGadgets -> Buttons) lines like

IF (M.id = Oberon.track) & ((1 IN M.keys) ) & Gadgets.InActiveArea(F, M) 
THEN ..........

have simply been changed to

IF (M.id = Oberon.track) & ((1 IN M.keys) OR (Oberon.New & (2 IN M.keys))) 
& Gadgets.InActiveArea(F, M) THEN ......

where Oberon.New is a Boolean that indicates that the user wants the new 
features. That means, pushing a Button can be done both with the middle or 
the left mouse button. In Texts, commands can also be executed with the 
left mouse, but the concept of double mouse clicks is used there. (they 
simply check if the mouse has moved in the text, if not: left mouse behaves 
like middle mouse).

For the Voyager plots, we have an additional module called vyEvents, where 
the System events are translated to Voyager-Events, that's for portability 
(V4, BlackBox....). I have there added an Event "doubleclick", which is 
time-based.

I am just now preparing the code and object files and all stuff of Voyager 
and Ants to be released in public under the LGPL license. I have to clean 
up some things in the next - say - two weeks and then a version will be 
somewhere on the net. I can send a note to all people interested in that. 
(Just ask me: friedrich at gsf.de) Actually, the software will also be 
availabe together with a book about stochastic image analysis ("Image 
Analysis, Random Fields and Dynamic Monte Carlo Methods", from Prof. 
G.Winkler) (in executable form and with all sources).

Felix.
