We've gone and made a very small change to our seyDoggy bloop! theme for RapidWeaver, bringing it up to r6. It became clear over the last few months that IE 6 transparency support in our navigation system was a nearly lost cause.
With the various hover states we needed for said system IE 6 was all but agreeable. Each and every fix caused more problems down the line. Considering the visual effect was only very minor, we decided that instead of forcing IE 6 to render the transparencies, we ought to just downgrade the IE 6 experience ever so slightly (with is actually an improvement now).
