Zooming in log file plots does not work correctly on Windows 8.1

[rrr6399]

I just recently bought a new laptop with Windows 8.1. I'm using the latest Mission Planner distribution. When I attempt to draw out a rectangle to zoom part of the plot, the rectangle is offset from the cursor like my mockup shows in this screenshot:

It appears that there is an offset error in the rectangular selection logic.

I just updated MissionPlanner to version 1.295 and build 1.1.5150.11972 and the problem with zooming on Windows 8.1 is still present.

does it work if you use a mouse, vs touch?

It doesn't work with the mouse, or the touchpad or touching the screen. Here is an actual picture of what I see:

I couldn't show it on a screenshot since the cursor and the zoombox don't appear on the screenshot.

I downloaded ZedGraph from https://github.com/discomurray/ZedGraph and compiled and ran one of the demos. It had the same zoombox problem on my box. So it looks like it is a bug in ZedGraph, which doesn't look like its being maintained much. (The SourceForge version is definitely not being maintained.)

yes, its an odd one, as it works on xp, win 7, just fine. so might take a while to get to the bottom of it.

I think it might even work on win8, just not 8.1

Looks like there is a bug related to changing the default screen text size: https://github.com/discomurray/ZedGraph/issues/3#issuecomment-35740945

The problem is fixed in the ZedGraph git repository now. I pulled it and compiled it. It works great now. https://github.com/discomurray/ZedGraph/issues/3#issuecomment-36048252
