Trying to resize the overall program window, especially on the diagonal seems like it's all of one pixel wide. I can't tell you the frustration that builds up over this over the course of a day.
@shaun.wall@cti.com, I personally use it on full screen mostly, but I just tried resizing at the corner and sides. Seems to work just like pretty much any other windows screen. I do not find it to be an issue. Please expand on the issue and/or include some screenshots highlighting the issue.
This is a Windows OS issue. See the following:
It is difficult to grab. I put the main window on a larger monitor and place the markups, properties and measurement panels on a my mobile workstation. I've learned to run the cursor at an angle almost parallel to the edge of the window an click when it grabs the border.
