Jack,
Check if you have write permission to the .net file. Alternatively,
you can save your topology in the new file.

> I downloaded R&S lab demo from Internetwork Expert and created a gns3 file

> All initial config files are in position as described in the IElab1.net
> OS: ubuntu 8.10 desktop AMD64
> linux kernel: 2.6.28-6, ext4 file system (ubuntu 9.04 alpha)
>
> Two problems:
> (1) The routers and switches are not in the order as R1 to R6, SW1 to SW4
> and then BB1 to BB3 in the "Topology Summary" window (right side).
> After adjusting the idlepc value for each router, I save the .net file and
> quit GNS3.
> Then I opened the .net file with plain text editor and moved the entries in
> order as you can see in the IElab1.net, but when re-opened by GNS3, they are
> still out of order as if I did not modify the file. What is wrong?

> (2) I spent about 30 minutes to have gns3 find the idlepc value with "*" for

> Then I saved the .net file and quit GNS3. After GNS3 restarts and reloads
