No mouse input to remote session

I am currently away from my office for 6 weeks and have both a laptop and iPad with me, both with LogMeIn clients loaded. Both were working fine, but the laptop, when connectd to the remote device, now fails to recognise any mouse input on the remote device. I can select menu options on the LogMeIn client but nothing selects on the remote host.

If I connect via my iPad LogMeIn app, it works just fine, so it's not the remote host at fault.

Any ideas?
