What happened to the map and model movement controls?

Why are the map controls so bad now after the update? You zoom in and the camera speed slows to an absolute crawl such that you basically cant move and when you are zoomed out it seems like the smallest movement sends you shooting into the black eternal never to see the map or 3D render again.

I used to use this software to 3D render buildings for damage assessment but I cant zoom in on damaged areas like I used to. Is there a way to change the control sensitivity in a setting somewhere?

Thank you.

The update came through several months ago. Are you trying to zoom in with your mouse wheel? Try a right click and hold and then move forward and backward to zoom in and out.
