http://www.wuala.com/grahamperrin/public/2010/11/14/b screenshot 001 highlights the icon for a difference pane (selected using option-tab) but no matter which icon I click (or select, they key Return):
- the lower part of the window remains stuck on Scan Local Drives.
A possible trigger for this oddity
Whilst preparing for the screenshot at http://openforum.sophos.com/t5/Sophos-Anti-Virus-for-Mac-Home/SAV-and-TimeMachine/m-p/817#M497 the list of menu items was displayed far longer than usual, and I moved the cursor to beyond the VM.
Workaround
A restart of the guest machine did not work around.
After a few hours away from both host and guest machines — whether the guest machine slept during that time, I don't know — the issue seemed to resolve itself.
I have taken a snapshot of the VM, and I might take a Console view of things, but there's no rush.
