Did you try to leave my usergroup.library and put -netinfo.device to devs: ? Probably those tools ask the OS for current username and netinfo.device is needed for that crap. I didn't build it yet because i was pretty sure applications can work without it.
Okay, i'll research the problem.

Hi, the netinfo.device don't work.
I took the usergroup.library form m68k AmiTCP and it works.

Error describtion :
When I load the Ambient CVS, all files have no "READ" Flag.
