@ingox Ahh...... that makes sense.
"coords" is much cleaner than "donecanvasdialog", works even in extended (of course) and will be easier to use for popups...... and for choice selection by moving gop windows, which needed some dirty hacks to get working with donecanvasdialog..
I like it.
And artefacts can be removed without a "map" message to the parent by clearing and redrawing the graph, in similar fashion to donecanvasdialog......... gop_switch_coords.pd

Hi,
I have some trouble with gop_switch_coords.pd .
When I change coords and go back, I have trouble with the sliders hsl, vsl. other gui's are ok.
The mouse interacts with the slider (if you connect it to a number, you can see the changing value), but the display is not refreshed.

The workaround is to send a [map 0, map 1( message to the parent patch, but it'is difficult for me not to use [iemguts/sendcanvas] for doing that.

Donecanvasdialog doesn't work well with pd 0.50, when zooming = 2
