Cannot edit hosts files

[admin windows kiabi]

Hello,

I can't edit a host file via "Manage hosts files" menu on HP SIM 6.2 last update.
When I create a new host, I choose the sample option and save my hosts file.
Then when I try to edit it, it is empty.
Whereas if I edit it with notepad, the file is correct.
Same thing creating new host file or with other old host file (which were correct with HP SIM 5)
I tried to reinstall all the software, but same issue. (installed on a VM with Windows 2k3 64bits, 4GB RAM, SQL 2005).
Any solution ?

Correct, that window does not allow for editing. You're doing the right thing using Notepad.

Will this problem be corrected ?
It was working well on HP SIM 5

Thanks
