Swede,
It seems your starfish was indeed partly orbed to another dimension. The aquarium should be able to correct impossible coordinates I think. On my system it changes ff ff ff ff ff ff ff ff ff ff ff ff to ff ff ff ff ff ff ff ff cd cc 8c bf immediately on startup. Assuming these are logical coordinates I put them in my program and took the starfish off the glass. Could you test again?
The 'Default' button is in fact the starfish on glass: "no" option.
James,
I followed your suggestion not to change the starfish position until the 'Apply' button is clicked.
patscarr,
I like the drag and drop idea. Never programmed drag and drop before, but it should be possible to implemented that and also keep the existing approach. I will look into it. BTW you don't have to click the dot, clicking on the fish also works.
