Can't remove event handler from .ipt

[meGVGMF]

Hi

Here's something I've never seen before:

When I try to remove an event handler from a part file and hit 'OK', I get this message, and the handler isn't removed.

I've tried removing it manually and programmatically, but both result in presumably the same error.

Any ideas?

Thanks

Oh I figured it out.

A coworker had inserted a content centre part as custom, and I thought it was one of ours. We've been adding event handlers to these somewhat blindly (with a script that manages the dialog for us, but the results of which we can't directly see), and so being able to see the event handler dialog I figured it was just a normal part that was broken, when really it was being protected from changes by Inventor.

Edit: Actually that didn't seem to be it. I tried reproducing the error and couldn't. It may simply have been the property set, or the file anyway, was corrupted, and wouldn't allow any changes. I simply deleted the generated content centre part file and placed it back in the assembly to regenerate it, and everything's fine.
