wxGUI: measurement tool does not show line after first click

[neteler]

In the current wxGUI, the measurement only shows the point of the first click but not the line attached to the mouse cursor. This would be helpful, though... I think it worked in the past.

The wxdigit line editor is working nice (and shows information in the status line about position), maybe use that?

Hm, I can see the line there. But it might happen that after some combination of map display tools it disappears. Does this happen to you with freshly opened gui?

Replying to annakrat:

Does this happen to you with freshly opened gui?

Yes. g.gui, Load raster map, "Measure distance", no line attached after first click. At a second click the line is drawn between the points.

I would note that the line digitizer tool in wxdigit is much nicer since it reports in the map display bottom bar rather than (unexpectedly) in the command console which is commonly not open.
