RhinoDotNetCrash.txt appears randomly

This is an issue that’s been happening for a while, and it’s not just an isolated case. For some reason, while using Rhino, this file gets dropped on the desktop. I would expect to see something like this if there was a crash, but it’s not related to a crash as Rhino seldom crashes, but these file show up almost daily. I think we’ve all learned to live with it, but I’ve had a few people ask me why, and I can’t answer them.


Here is the file:

RhinoDotNetCrash.txt (4.1 KB)

FYI…We are up-to-date with service releases.



Hi Dan - here too, sometimes - I have not seen this in a while but there was a rash of these some time ago, it went away, and again once in a while recently. I was about to log a bug but it ceased again. - I am not sure it was ever fully diagnosed - @brian will have a better idea.


This specific report looks like the result of a custom python script with some user interface. Does this show up when running some custom python scripts?

I have a few scripts using ETO for the UI. I will see if I can find one (or more) that trigger the creation of this file.
