I now have 3 clouds on my topology and when I try and delete them i get the following error in the Dynagen console:

I've tried to delete the Clouds entry in the .net file, save and restart GNS3 (ver 0.7)..but the Clouds are still there.
It's starting to look like a stormy topology with all those clouds ;-))). How does one nuke them.. permanently?

Well, I need to fix that ...

Thanks for reporting.

Fixed

Hello Everyone,

I had the same problem but managed to fix it by clicking on the history commands in the "undo stack".

Grossmj, you say it's fixed so what shall I do to fix mine? do I need to download GNS3 and install it again?

regards,
Nidal
