Hi!. I'm using VMWare Viewer and i have a big problem. When i switch to unity mode i got a problem (that is very irritating for me): when i try to use the key combo alt gr + <key> it doesn't work. Now, i've searched a lot on the web and the cause is that the os recognize the alt gr key as left ctrl. Some guys on the web suggest to edit the /etc/vmware/config file by adding some lines which indicates some keycode for the keyboard map but this solution doesn't work for me. Is there someone that can help me? 
Thanks in advance.
Note: the version of vmware which i use is the last avaible for the download from the site.
