using transparent aterm

[Robert Brimhall]

Hi all,

New Xfce user... this desktop is amazing... on par with my other
favorite ROX! Anyways, I seem to be unable to configure my terminal to
launch a transparent aterm with this command 
:aterm -tr -sh 50 -fg white -bg black:

xffm claims this command is not valid and reverts back to the generic
xterm. What am I doing wrong? I set this globally with the settings
manager.

Also, can I change the default "browser" to Mozilla Firebird or Galeon
rather than Mozilla? Can't seem to figure out how (including within the
left-click menu displayed when clicking the desktop). Any help
appreciated. Thx!
