The editor is so bizarre -.-
Just tested it myself to confirm and it's indeed where the problem is. If you have your editor set to MyCode, the tooltips won't work. Why you ask? I have no freaking clue lol. But if you have it set to SCEditor or SCEditor Source, it'll work fine. Up to each individual if they want to change it or not. But if you do, just go to "Edit Options" in your profile and go to the drop down menu in the lower right. Then select either "SCEditor" or "SCEditor (Source Mode)."
