TableArrangement issue

[Tariq_Mehmood]

Dear Experts

I have a table arrangement, it has 4 columns and 4 row.
When I try to copy any contents from a table cell and paste to another cell then it leads to this error

After this error, the project looks like this

Suddenly every format disturbs, unfortunately there is no UNDO.
What should I do now?
Please

Export the project .aia and post it here, for post mortem.

Then remove the table arrangement and use Horizontal Arrangements inside a Vertical Arrangement instead.

1. Delete your latest or all of your components that you copy/paste.
2. Save your project.
3. Reload http://ai2.appinventor.mit.edu.ezproxy.canberra.edu.au
4. Load your project once again..

How do i fix this?
