Update: The problem described below only happens in Internet Explorer. I will be opening a ticket.
When time is entered through the time log, the estimated hours remaining is automatically calculated. However when entering hours from the Activity Center, the estimated hours are not automatically calculated and must be manually adjusted. I don't know if this is by design, but it is problematic.
Would it be possible to have the calculation be automatically updated and refreshed while still allowing manual override? Or maybe skip the manual entry option but still make it automatic (like time log entry) since manual adjustment is already available through activity center anyway?
