To Reproduce:

1. Open attached project and choose Window>Window Test
2. Click "Add Window" twice
3. Enter unique text in the six fields
4. Open the script, and re-save it to force a recompile.
5. Click "Add Window" twice.

Results:
After one or more tries some of the text fields of the new windows will be filled with data from the previous windows before compilation. Sometimes two fields will have the same text, and typing in one will cause changes in both fields.

Expected Results:
All new windows appear with empty text fields. When editing text fields, only the selected field shows changes
