Captivate 6, serialized WidgetProperties leak, lead to Project File Size increase

hi,

using Captivate 6, serialized WidgetProperties leak, lead to Project File Size increase.

Step to reproduce:

1. Create a project
2. Insert Widget on which you can add image or text
3. Copy and paste them, or insert other widget and repeat step 2
4. Save the project
5. Delete all the widget
6. Save the project
7. Repeat the process several time

The Captivate project .cptx file size increase a we repeat step 1 to 7 serveral time.

Thank you for any ideas!
