If I select Tools - Preferences, or Tools - Script Editor
the File Edit View Insert Format ... is grayed out, and if I click anywhere in Freemind I hear a ding, but no other Freemind window is available. After ESC other Freemind items are again clickable.
All other Tools menu items work as expected.
Freemind Version 1.0.1
Host OS: Windows 7
Java: Platform 1.7, Product 1.7.0_51 (build 1.7.0_51-b13)
P.S. Thanks for Freemind!
