viewport orientation issue

[jetdog6]

Hi All,

I'm going through a fairly large area, about 2,000 acres looking for issues with point classification.  However the viewport orientation keeps getting all screwed up just from panning and selecting points/assigning classes.  It's so bad I have to save, close the project, and reopen it to fix the issue.  It's hard to describe, please see the video below for what it looks like when it's screwed up, and the picture for how it's supposed to look.  Hitting the "reset viewport" sets it to some random position where everything is sideways, does nothing to fix the issue.  Thanks for the help!

Hello jetdog6,

Is it possible to share the project (with only cameras, markers, shapes and tie points in order to reduce the data size) to support@agisoft.com, so that we could try to reproduce the problem on our side?
