[GRASS-dev] [grass-code I][451] "place with mouse" gets confused when placing several different layers

[Michael Barton]

Moritz,

Could you try with clicking inside the coordinate box of the layer desired
before trying to place with a mouse? Also, I've had luck with deselecting
and reselecting the place with mouse check box for a layer.

This is kind a hack, since you can't really place these items interactively
with the current setup (but you can with wxgrass). What is going on is that
clicking with a mouse will pick up screen coordinates, which are then passed
back to the coordinate field for the layer in question. If the desired layer
is not active the coordinates will end up in the wrong box or it won't be
able to find the box it is supposed to put them in. There may be other
causes that make the coordinates end up in the wrong layer too.

Unfortunately, the TclTk error is not more informative than the above
summary.
