That's called Frame Edge Highlighting and it cannot be turned off. However, only the two Arrow cursors activate the Frame Edge Highlighting, you could switch to another tool.
I'm still baffled how people are upset or not happy with this feature, I find it's great. I didn't even notice it until someone mentioned it.
Anyway, Frame Edge Highlighting is covered in the Help Files.
As is Saving Back to older versions.
Both have been TALKED TO DEATH
Harbs of InTools gives a brief description on why backsaving is quite difficult for InDesign engineers to do

I never got that hate for the highlighting either but it worth noting that you can turn it off in CS5.5.
Ah I thought that but wasn't 100% sure. Thanks for letting me know.
I imagine yo are really talking about CS3 and CS5, which are versions 5 and 7, respectively, not 3 and 5. Might not seem that important, but the features and capabilities of each version change dramatically and wee need to be clear.
If you read the links inthe posts above you should by now understand that ther is no way to go dirtectly from CS5 to CS3. You need to go through CS4 to get there, and the seults may not be waht you expect. Your other problem, though, seems more like a user issue than frame edge highlighting. Objects don't move, in any version, unless you actually click on them. Frame edge highlighting only shows you where things are, it doesn't select them or move them.
