It sounds like you have 'Enter' in the macro or on the XKeys. 'Enter' key is usually keybound (by WoW default) to open the chat window and then the macro is running. Just a thought...

Can I assume you are putting the macro in the Xkeys configuration Program, Macroworks? You use Macroworks to programs the X-Keys with a single key. I cant remember of the top of my head but you should find the info in the manual. Once you have programmed the key, you make the macro in wow and bind that key to it.
FYI, I believe Macroworks is only for the USB XKeys and not for the PS2 version.
