if I run an OLS regression and, from the menu of the model window, I

I run gretl from a console and when I click on the little mouse in
the labels dialog box, I obtain the error "Couldn't get coordinates"
This means gretl can't map between the mouse coordinates on screen and
the data coordinates for the graph, because it has been unable to get
the necessary information from the gnuplot graph (e.g. where do the X
and Y axes start and end, in data space?).
This could be due to a number of things, related to the gnuplot
version and/or the language setting (the issue of the decimal
separator -- though I thought I had that fixed!).
I'm having difficulty replicating the problem here. If you have time,
could you give me some more details (gnuplot version, and details of
the graph would be useful: you said it was a residual plot, but it
might be helpful to know from what regression). Thanks.
