If you already have CM7 installed do you still need the latest webos doctor?

Will this work on OS X Lion?

If it booted back into CM7, you didn't do everything.
Sounds like it didn't find the CM9 file. Did you rename it? Try DL'ing it again. There's something wrong with it.
You can close tabs by pulling your thumb in to expose the controls, and hitting "X" - but if you want the controls gone, just pull your thumb in to expose the controls, hit the three dots, and select settings. It's under Labs.
edit: do you not know how to expose the thumb controls? You have to drag your finger in from the edge of the screen, either the right or the left part of the screen, and a little popup will appear with controls on it.
I just did everything and it ended up booting back into CM7. Should I have deleted all of the CM7 files from my TP? I guess that would make a bit of sense.
Also, is there another hosting site that has the g-apps and the fixer? Megaupload has been seized and is non-functional. Damned government.

You must be my new proof-checker.
The gApp fixer file, probably not needed any more, was the 5th file. I missed that when I updated to guide and removed the fixer file.
The original Acme installer was a zip file with the script and instructions. They decided to release just the script now. It's actually a text file, but if add an extension, it won't work.
It's been updated. You should be good if you remove the extension.
