In the newest version of OmniPlan, there appears to be a bug where the Gantt chart window is mis-specified. I first encountered this when I tried to load the report and see the following:
This persists regardless of the timeframe that I have set my window to in the project viewer (annual / monthly / whatever). I first thought this was a report issue, but if I tell OmniPlan to “Scale to fit Project”, I get the same issue.
Seems like it’s not getting the size of the window calculated correctly somewhere along the way.
