Alan - unfortunately the issue is remaining for me (us?) after the 5.3 update.

with the dyna-view un-rotated, the desired point symbols appear where expected.

however, when the dyna-view is rotated to the desired orientation, the point symbols disappear.

and are displayed at a unexpected location.

Please advise if I (we) are using the product not as intended or if the defect remains. If it continues to be a defect, please encourage Trimble to release a patch as soon as possible.
As always, thank you for your help.
