A dialog box should come up saying that the window is not available on 64-bit 
architectures. Does that appear?

Per discussion on last week's conf call, per Andrew, this window is supposedly
working correctly and has not (yet) been enabled as an oversight.  I disabled
the dialog pop-up in my local tree to verify the correct working of the memory
window on x86_64 and found it to not come up at all.

As yet, in the official tree, the dialog pop-up is still enabled (for this reason).

Is your machine an EM64T or AMD64?

Steps to reproduce:

1. Execute: tail -f <somefile>
2. Start a frysk debugger session (using the GUI) for that tail process
3. Open the memory window

I am able to open the memory window without problems on both Intel (R) 64 and 
AMD64 on a regular process - however, the `tail -f testfile` prevents me from 
even opening the debugging window due to a spinning ptrace error.

After some investigation, it turns out that the problem is that the spin buttons
are defined (in glade) to have an upper bound that is well below the limit for
64-bit addresses, causing truncation in the address and thereby a ptrace peek at
an invalid address.

2007-06-20  Kris Van Hees  <kris.van.hees@oracle.com>

        * SourceWindow.java(toggleMemoryWindow, toggleDisassemblyWindow): Do
        not display the dialog for x86_64, and changed the message to simply
        state that the window is not supported on the current architecture for
        ISAs where that is still the case.

2007-06-20  Kris Van Hees  <kris.van.hees@oracle.com>

        * memory/MemoryWindow.java (setTask, resetTask): Set the valid range
        of the fromSpin and toSpin buttons from 0 to the highest address for
        the task's ISA (2^wordsize - 1).
        * disassembler/DisassemblyWindow.java (setTask, resetTask): Set the
        valid range of the fromSpin and toSpin buttons from 0 to the highest
        address for the task's ISA (2^wordsize - 1).
