The pen tool in InDesign no longer shows the plus or minus sign when hovering over a path. I can still add and subtract points to the path, but it's hit n miss without the plus/minus sign. Troubleshooting that hasn't helped so far: deleting prefs, restarting the program, restarting the whole system, updated from CS6 8 to 8.0.2. Am I missing something obvious? OS: Yosemite / iMac
I'd make sure you restored InDesign preferences completely. Here are instructions:
However, you still should have the Add Anchor Point and Delete Anchor Point tools under the Pen tool which should work.
It's also possible some third-party software could be interfering. Try running InDesign from a new user.
