Problem

When running disc mapper analysis (in the field map stage) the progress is stuck on 10% whilst the tool runs the biphase observer for all fields (which can take a long time). It looks like the application is hanging.

Proposed solution

Make each part of the process update the progress - what is it doing + 0-100% per part (rather than trying to get it all in one 0-100% scale.

Alternatives considered

Not fixing it :)
