Google infowindow is not displaying correctly using their API

I am using the Google map API to integrate the map into my website, I am using custom markers and infowindows. I have used this previously with no worries but now, when I click on my marker, the infowindow displays incorrectly.

I have tried to many different things to try and fix it but I just can't seem to figure out whats going on.

here is an image, I can't attach it to the post since I am new and all that.

Any help would be muchly appreciated.

Thanks

Did you change your DOCTYPE recently? I once had the infowindow start doing funny things like that when I switched to a different DOCTYPE.

Well, I thought I had fixed it, but it turns out I didn't. To fix it I had to turn the the dreaded iframe. Sadly, it will have to stay that way until I find a better fix.
