I will fix this bug. However I would note (especially since you praised me for following web standards) that the W3C advocates against opening links in new windows. In fact in Xhtml strict the target attribute is not valid so when I fix this bug and you use this functionality your page will not be xhtml strict compliant.
The W3C logic is based on the idea that the user should be in control and browsers all give the user the ability to open links in a new window or tab and forcing that upon them is generally confusing and takes control away from the user. Unfortunately, opening in a new window has become such a widely used technique that often users now expect it and some argue its confusing the user if an external link doesn't open in a new window. Myself I side with the W3C on this but I don't expect everyone to agree with me so I will fix this bug but I will never use that myself and I wish everyone would follow the recommendations.
To me if I put a link in the menu its ocnsidered part of my site so it should not open in a new window even if I thought external links should open in a new window I would not put exteranl links in my menu unless I was trying to integrate 2 sites into 1and then I would not use a new window.
When I first learned about the deprecation of the target attribute in xhtml I didn't agree with it but now after more groking on the matter I totally agree with the W3C, its usability 101 to keep the user in control at all times. Now if only more people knew how to right click a link and open in a new window when they want to and if sites would stop doing that for them the web will be a better place.
