hyperlinking an Image using the HTML Editor does not work.

Hyperlinking an image using the html editor gives strange behaviour using different browsers.....

In Firefox (I'm using 1.0.7), try this.

insert an image, give it a useful alt text - eg "image"
then make sure the image is selected and use the hyperlink button to create a hyperlink for the image.
for the hyperlink title use some useful text like "URL" - then hit ok.
Instead of creating a hyperlink, in Firefox, the Image disapears, however the image alt text appears in place of the image as "text" (If that makes sense!)

In IE 6 you get a JS error like mentioned here:

In IE 7 (Beta 2) you don't get a JS error, but when you try to add a link to an image, the insert Link window doesn't do anything when you hit "OK" - it just sits there, and makes no changes to the underlying window (this is possibly just an IE 7 quirk, - might be improved in the next version....) - I'll upgrade to RC 1 to see If I can get any more debug info out! ( I will upgrade FF as well to see if that makes any difference.
