Customer reports the following problem when testing JRE 1.5.0_11 on Windows Vista. An applet, using the Windows look and feel, hangs the "Internet Explorer 7.0 for Windows Vista" process when trying to open a JFileChooser file dialog. The Internet Explorer 7.0 process can only be stopped by ending the process in the task manager. The same applet code, but wrapped into Java Application works fine, when run outside of Internet Explorer 7.0.
 
Steps to reproduce
 
Start Internet Explorer 7.0 on a Windows Vista machine.
Open a page with an applet using the Windows look and feel.
Perform an action in the applet that causes a JFileChooser dialog to appear.
While reproducing the configuration of Internet Explorer was changed so that the "Protected Mode" of Internet Explorer 7.0 for Windows Vista was disabled for the security zone of the applet's HTML page.
