I encountered this bug recently too. It appeared in the GTK* backend
where the button release event appeared to be ignored. Were you
running on GTK*?

Yes - I just checked to be sure: GTKAgg (sorry for not mentioniong this).
The problem is only there for GTK*.
Some remarks: I used the following script

The buffering does work with TkAgg, but not with GTK*,
and also not with WX*, so it might be not related.
Do you have any idea what has changed since 0.82
so that the buffering does not work anymore?
- for TkAgg one gets a pretty unpleasent "breathing"
of the plot window because the string for the mouse coords
changes its length
(it gets even worse when switching to zoom to rectangle mode).
A solution might be to generate a string
representation of the coordinates
for which the number of digits is constant.
