=====

I if another mouse operation is attempted immediately after a drag and drop operation on the JavaTest summary window the JV segfaults.

To reproduce:
> cd JCK-11beta2
> export CLASSPATH=/usr/java/lib/classes.zip:./classes
> java javasoft.sqe.harness.Main

In the JavaTest GUI open lib/vm-jdk11.jtp and press start. When the tests begin executing attempt the operation described above.

SIGSEGV 11* segmentation violation
    si_signo [11]: SIGSEGV 11* segmentation violation
    si_errno [0]: Error 0
    si_code [1]: SEGV_ACCERR [addr: 0x0]

Sorry, but this definately IS reproduceable. In any of the JCK manual tests
if I highlight text in a textbox and drag it and click immediately before the
dragging text disappears I can get Java to dump core. SunSoft has a fix for
this and it's verified.
