Cannot access any Reference Help files

Hi, I've just installed the Arduino software, and have the Duemilanove board. I cannot access any topic under the Help tab; the error message says: "There was a problem sending the command to the program". The Reference files do exist and I can access them through Windows Explorer.

I use Mozilla on Windows XP as a browser.

Could it be a browser permissions issue?

Any help appreciated, thanks.

You could just bookmark the online files:

Why would he want to do that? If he must use a bookmark then it seems to me that he would have faster access if he bookmarked the reference files on his own computer.
