I have had a problem with Rhino V7 hanging while opening large V6 files. Rhino just sits there with a big white spot. I presume there is some dialog box that wants to be displayed.’
I’ll try to upload and link to here.
Does Import of the same 3dm into a new document hang as well?
No. They open fine when imported. At least for the several I have tried.
Thanks for checking that. Can you private message me one of the files? My guess is that there’s a display mode the file was saved in that is causing the hang and Importing gets around that.
My suspicion as well. How do I sent it to you? I uploaded on to tech support. I’ve got some more.
