Release 4.619 introduced a bug which broke ability to run manual backup by breaking the backup progress screen: screen would pause with no activity/progress. (Online backup was fine). The nature of the bug meant it may of affected other screens too (none I am aware of though).

Also finally got Husky F12 availability check to work again!  Turns out it was working fine on non Windows systems (Linux/Mac which myself and James use to build/test) but wouldn't work on Windows. Should now be working again on all.
