Whenever I get stuck with a CS4 issue, I do what any smart, tech-savvy, genius-type person would do…I Google. If you’re trying to find the answer to this issue: “Illustrator CS4 Selection Tool Won’t Scale”, you’re going to get a lot of results…but if you’re having the problem I was having, all of those results will be WRONG.
Feedback indicates this fix also works for newer version of Illustrator (CS5, CS5.5 and CS6).
When you are using the Selection Tool in Illustrator CS4, you cannot scale objects. You can move them but you cannot re-size or rotate them.

Still not working? My problem too.
Save your AI projects and close the program. Re-launch the program and immediately hold “SHIFT + CTRL + ALT”, continue holding until AI opens. This will reset your AI preferences…PROBLEM SOLVED!
