I have a problem with nifskope

It crash when openning a fallout mesh and clicking on it in the viewer
i can rotate it click on parts in the block list but everytime i click on the model in the viewer it just crash

and that's really a problem as i wanted to modify some mesh :cryvaultboy:
(i really don't know why it happens)

It might be the mesh. Is it the M1D Garand model from the mod with the same name at nexus? That model crashes nifscope for me too if I click it but selecting the nodes in the tree structure on the left works fine so try that.

I saw this once before. I believe it was related to my video driver when I installed Windows7.

No it's not that mesh it's some armor (one from tailor mod for a part)
It just don't want to do what i want
I can't copy mesh and insert it on another instance of nifskope, it just copy something that as nothing to do with what i copied on the other mesh

I just want to change a part of an armor with another one

I can barely select things on an older version but i select what it want and nothing else

edit: my video driver is up to date
