This may be more appropriate in the GNS3 forums, but I'm not a member there

Since my current physical routers aren't SDM-capable (2610's) and I've gotten GNS3 working, I thought I'd try tinkering with SDM on one of the virtual routers made. I managed to get it working after a few attempts but for some reason it seems only semi-functional. I can create a new connection, but I can't edit existing connections, and the 'Additional Tasks' .. button? doesn't work at all (it's clickable, but the right-panel remains on whatever screen it was on before).
Note that I'm running SDM on my PC since so far I haven't been able to 'upload' it onto the V-routers; perhaps that's why some settings seem disabled? I'm just curious if anyone else has used these tools together and if they had similar issues or if it's something I can look into further to try to fix.
