I have also experienced lockup today for the first time.
This has never happened to me before through many years of using Mobile sheets.
Mobile sheets worked flawlessly through rehearsal; start the performance, try to move to the first page change and no response.
I was not using the metronome, audio file or anything else.
This was most upsetting for me and the rest of the music group as the only way to fix it was to restart the computer. (And the performance)
I use the windows version on a surface book. Nothing else is running on the computer but mobile sheets.

To avoid this happening again at a critical time, is it possible to roll back the programme to a previous version which was working OK.
I can not trust the present version to work without locking up.
Look forward to your reply.

Did you have wi-fi on? Even if no other application is opened there are MANY (unnecessary) services running in the background in Windows OS.
You should disable most of them if you want more reliable device and do not connect it to the internet.
Windows is not the best choice.
