[VW7.2.1] ImageEditor causes virtual machine to crash in Linux

I have a 800x600 bmp file. I read into VW as follows.

ImageReader imageFromFile: 'colors.bmp' toClass: DummyTree selector:
#colors

I start ImageEditor, load the resource DummyTree class>>colors. VW
disappears from the screen totally.

Is there a better way to get a photo size *.bmp or *jpg into VW and
view it there?

Thanks,
Koh

To view the image, you can do something like

ApplicationWindow new
component: (Wrapper on: DummyTree colors);
open

(I think in the good old days it would work even without the wrapper,
but things change).

As for the ImageEditor, "don't do that". ImageEditor can only work with
small images, and even for those it's worse than primitive. If you want
to edit the picture, you are better off doing that in a real image
editor, and importing it afterwards.
