Hi
I'm trying to create a virtual table, as i tried to use the free form editor in the
virtual table, i'm getting the below error, i tried so many times restarting the
application but no use at all, i couldn't even type a single word,

anyway to post screenshot here?

error

You can't post images directly, but you can post them on an image hosting site and refer to that from here.

There may be a patch that addresses the problem in the free form editor.
