I just did a Google search for "Widget Framer" and did not see any auto-spelling-correct nor did I see a SERP weighted heavily toward "Widget Frames."
Before I published the above post, I did the same search as keyplyr did, and some other searches too, and incorrectly concluded that what the OP had posted was an example, not an actual site name.
As it turns out, the domain is apparently penalized. Only a search for "widgetframer.tld" would bring it up, and that's a sign of Google penalization. Searching "widgetframer" by itself does not suffice to return the query... It needs the tld if penalized. So the following examples do not apply to this original question any more, though they may have at one time. They do apply to the general question of Google and autocorrected misspellings.
In my experience, Google currently will autocorrect without asking you only when it sees that the odds are very strongly in favor of a misspelling... ie, it finds essentially no examples of the searched term in the index, and many examples of an alternative.
I'm going to post an actual query I've tested which is so common that there's no problem posting it, and also a slightly obscured example, which should be clear to readers here. I'm not posting the actual vocabulary because I don't want it to distort actual results... and posting on WebmasterWorld can do that.
The situation should be analogous to the OP's, in that last letter of the query gets changed to a much more common spelling. In this case the terms are...
a) lady gaga
b) l*dy g*gs
Searching example (b) resulted in the final "s" getting changed to an "a" in some circumstances.
Searching for...
[l*dy g*gs]
No quotes on the comparatively rare query caused Google to assume a misspelling, and returned results for lady gaga, along with the message...
Search instead for l*y g*gs Using quotes to force the exact query caused searches for "l*dy g*gs", or for "l*yg*gs" (the latter without the space, and with or without the quotes), caused Google to return the correct results, but Google, still in a questionable range, asked:
Did you mean: "lady gaga" In a normal situation, without a penalty, more awareness on the web and real traffic for the search query would change the suggestions. I would not try to game the autosuggest tool.
For an old discussion on a more aggressive autosuggest test Google ran, so you can see how much better things have gotten ;) ...see....
