Log message:
2006-09-15 Mike Cvet <mcvet@redhat.com>
* SourceWindow.java (toggleDisassemblyWindow): Added a catch for 64-bit
architectures,
on which the disassembler does not work properly, yet. Fixes #3203.
(toggleMemoryWindow): Ditto.

* actions/ShowMemWin.java (execute): Added a catch for 64-bit
architectures, fixes #3203.
The Memory and Disassmbler windows do not yet work on 64-bit architectures,
pending the inua bugs.
