Hi @peter_5488,
Thanks for reaching out and for sharing the screenshot. That "PARM" error definitely looks odd and shouldn’t appear when using the bounding box or Free Transform tool. Could you let me know which version of Illustrator and operating system you're using? Also, does this happen with all files or only a specific one?
If possible, please try resetting Illustrator preferences (make sure to back up the preferences before resetting) to see if that clears it up. You can also try testing this in a new user account or safe mode, which can help rule out any system-level or third-party conflicts. A short screen recording of the issue happening in real time would also help me get a better look at what's going on.
Looking forward to your update.
Abhishek
