I have interested in this topic.
issue1 and issue 2
==============
Please confirm that you select Mac Profile for your pariticular Snow Leopard Server through Settings==>Keyboard&Mouse ==>Mac Profile.
issue 3
=======
"Command - C" is for copying selected item/text to the clipboard; I guess you use "Command - W" for closing the current application. again, please confirm that you use the correct Mac profile.
Issue 4
======
if you press "Command -Q", the expected result is to close Fusion application and all of running GOS will be suspended or powered off which depends on your settings from Fusion menu==>Preferences==> When closing a virtual machine.
if you would like to close/quit application within your GOS, Snow Leopard, please confirm the following items is unchecked.
settings==>Keyboard&Mouse ==>Mac Profile ==>Fusion Shortcuts===> uncheck the checkbox "Quit" which means GOS interpret the command itself instead of sending to Host OS.
