The 'Tree' panel nodes are overlapping each other. Steps to reproduce:

1. Clear out 'Regular expression' and 'Target string' fields and restart Regex Coach.

2. Click on 'Tree' tab.

3. Enter some text into the 'Target string' field.

4. Enter ^[\w\W]+$ into the 'Regular expression field.

5. Change the regular expression to [\w\W]+ by deleting the ^ and $ characters.

6. The tree map crashes together, and even if you clear out the 'Regular expression' field you still see the tree.

You can also view the attached video to see what I'm talking about.
