I hope this doesn't duplicate what I seem to have lost, but you deserve a reply, so here it is again.
Thanks for that. Your remedy left Snow Leopard behind, but I can live with two icons. As to your "drag and drop," comment, which I just noticed, I never thought of that. If I had dragged them to the trash, which is what I assume you're saying, I would have had the same worries. I assume that you are saying that it would have been perfectly safe to have disposed of the icons in the trash. If so, why did you suggest the remedy you did? Just to be sure, can I trash the Snow Leopard icon without fear of causing unintended damage?
I meant, in place of the icons you took off the desktop, not the ones remaining. The way I showed you is the only way to hide the ones that still remained on your desktop after using that app.
It depends what the Snow Leopard disk is doing.
if it is an install of SL then yes you can delete it/eject it.
no, moving the icons that still remain to the trash, would not have solved your issue. The only way is the way I showed you.
