Bloody hell, that was scary. I just opened up Powerpoint on the Mac to go through my show for next Friday, and ALL the text was garbled. I mean nonsensical, complete gobbledigook. I opened up a previous version, same thing. WHAT???
This would mean no show. I was panicking. Then I looked at the text and realised it had done a Caesar shift one space to the right, so that 'Good Evening' became 'Hppe Fwfojoh'. Was it a virus? I opened up other files and exactly the same thing, so at least it wasn't just the version that I'd just done a week's editing on. The fact that the whole program was consistently weird was slightly heartening. So, like you do, I shut down Powerpoint and re-booted it. Massive and huge sigh of relief. All was well.
Well what on earth was all that about then?????
