(I don't have to edit any files). 1. wr mem 2. gns3 file menu save. Or icon save. 3. delete the contents of the working directory. 4. (optional) I noticed that if I have created a vlan database in the EtherSwitch Routers, it appears to be stored in the files with naming format of c3745_Rx_slot0, so I haven't been deleting the _slot0 files in the working directory, and the vlan database is preserved. Finally, Now I can focus on the labs and not worry about losing my work. Perhaps this will help others using GNS3 v0.7.4 on Windows XP.

Then it rebuilds the files when you start it. Perhaps it's the fact that I'm deleting the contents of that directory and forcing a rebuild that is correcting the problem, but it has been working for me if I do both.

Hope that helps someone, cuz it took me a long time to figure out. In gns3 0.7.4

edit the topology.net file like so:
workingdir = .\working

By default, the .net files get this in my install:
workingdir = working

but I have to change it to this:
workingdir = .\working

Then it works for me.

Hope that helps someone, cuz it took me a long time to figure out.

Why would you create a program that doesn't let you save your work? This is just plain ridiculous. Did you guys even test this program out before releasing it?

Router#write then router configuration file will be saved on your Temp file. *.cfg when you open gns3 next time, it will load the *.cfg by itself. you try it.

Router#write

I close gns3 and ran task manager , but no process related to dynamips such as dynamips-wpx.exe was there . My workaround was to use from external hypervisor . but in external hypervisor the first router that I put in screen is R1 not R0, and how can I use from hypervisor manager again ? (I am using win xp SP2) Thanks. When I drag a router into screen ; it says hypervisor is already on port 7200 .
