Since Gnuplot 4.0 is now officially out, and it has this feature, I suspect 
you are going to get more and more reports about this (it only used to be 
available to CVS users, which is a far smaller group).

I'll try to whip up a decent patch against 1.7 tonight and send it your way, 
hopefully covering all the bases.

Cheers,

Coincidentally, this line was added at the suggestion of another user,

One quick-and-dirty fix would be to defer the initialization of the 
terminal until the first plot (or splot) invocation.  But I suppose that 
a cleaner solution should be possible.  However, I'm at a loss regarding 
the best solution, since I've still never even used a version of gnuplot 
with mouse support!
