It works fine. But I have one big problem in a special project:

From time to time I get an error message like the following:
Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: Column 3 is not available

After this error message the application is frozen.

The problem is that I cannot reproduce it.

When I restart the program and try the same, it works...

Do you have any idea what it can be?
I searched in the forum, but I did not find a solution.

Thank you in advance for your efforts

Here is the complete error message:
