by 'maximize window' you mean you switched NetBeans to full screen mode or maximized the main IDE window or maximized browser window within the main IDE window?
Comment 3 Petr Jiricka 2012-09-04 14:18:46 UTC
I believe I maximized a TopComponent within the IDE by double-clicking the tab.

I get this problem when running a webex session of my Netbeans platform application.  Webex seems to do something that resizes the window which causes the error to appear.
