Hi dm319, welcome to the Linux Mint forums
Thanks for joining the forums! When running MATE you might consider upgrading to version 1.4. It has more bugfixes for the old GNOME 2 code, and some new features. See here: http://mate-desktop.org/2012/07/30/mate-1-4-released/
. If you want to upgrade, the steps for that are here if you don't want to wait: viewtopic.php?f=206&t=111533&p=624015#p624015
Be sure also to check out the Community
website (tutorials, hardware and software reviews, ideas). You can also chat in real-time with other Linux Mint users. In the Mint Menu, in the Internet section, start the application XChat IRC. You will automatically get connected to #linuxmint-chat for general chat and #linuxmint-help for support with other Linux Mint users.
Have fun with Linux Mint.
