pulldown menus stay open while window is begin dragged (Solaris ONLY)

Build : 'H'
OS : Sol 2.5.1, 2.6 (2.7 untested) ok on Win32
app : SwingSet demo {/usr/local/java/jdk1.2.2/solaris/demo/jfc/SwingSet}

A UI bug. Using the SwingSet demo located in the JDK build dir:
/usr/local/java/jdk1.2.2/solaris/demo/jfc/SwingSet
execute: java -jar SwingSet.jar

If you pull down any of the system pulldown menus then grab the title bar to drag the window. The pulldown menu will persist in it's original location while the window is no longer at it's current location. Expected result is for the pulldown menu to go away.
