What happened browser-wise? Some strange things.
Take it for what it is worth - but this embedding of Google Groups in Blogger has up to now worked without a hitch in Mozilla Firefox and Google Chrome.
Internet Explorer produces a garbled message about not being able to embed frames and does not show the forum at all. Not usable.
Opera has one line of overlapping text -- a serious-enough error to deter usage.
I checked it all out again by using Lunascape 6 to access the Lawpundit blog.
At Lunascape you, where you can toggle between the Gecko, Trident and Webkit enignes for the major browsers:
- Gecko reproduces the Google Groups LawPundit forum in the LawPundit Blogger blog without fail
- Webkit overlaps one line of text
- Trident the first time around gave a runtime error and an otherwise blank page and at the second attempt produced most of the page, but without the forum and with the message: "ERROR: Possible problem with your *.gwt.xml module file. The compile time user.agent value (ie9) does not match the runtime user.agent value (ie8). Expect more errors."
In any case, those results match my own browser usage of Firefox as the browser of choice (because of all the options), Chrome as a good backup (but limited, option-wise), Opera good but sometimes buggy and eccentric, and Internet Explorer is simply too flawed and not worth the money.
