Activating JMenu in Java2Demo.jar causes it to lock under Win32

Build : 'G' (Does not fail in 'F')
app : Java2Demo.jar
OS : 95/98/NT

By simply doing a mouseDrag over the JMenus in J2D you can get the app to hang.

Steps:
1. Activate the JMenu "File"...keep your mouse over "File" item
2. drag your mouse over to the next JMenu item "Options"

- if it doesn't hang by now simply hover your mouse over the two items back/forth and within just a couple dragovers it should lock.
