AW & Hyperlinks

Recently I've been having trouble following links on AW, usually ones posted in the body of users' posts. In one case, someone linked to a blog post. Trying to open it in a new tab sent me to www.absolutewrite.com/undefined . I had to actually copy the link URL and paste it to my browser to get it working.

Today I had the same issue when trying to check out a link to a book trailer posted here: http://www.absolutewrite.com/forums/showthread.php?t=213822 Strangely enough, I went right back to that link and it's now working.

What's going on? I'm using the same browser I always have, nothing's changed between then and now. Is this a bug with AW?

Mac OSX 10.6.7, Safari. It very well may be. I've been trying to puzzle out what I'm doing that may be causing this. I think I may have tried 'copy link location' and pasted it in a new tab, ended up getting the weird AW page. When I went back to the post, the hyperlink url was the AW link. Refreshed the page, suddenly it was a working link again.

Weird, weird, weird.
