This machine is running Windows XP Pro on an Intel Pentium M processor with 504 MB of RAM. An attempt to run Word Perfect 9 gives a little pop-up message with the title "Perfect". In the message next to the familiar X it reads "Out of memory 15" then and gives nice little "Ok" to click on. After this Word perfect is kind enough to start up. Any attempt to actually open a document results in a short wait before the familiar WinXP error reporting window pops up. After this the application quits.
