Editor Consistantly Crashes After Loading a Scene

I’m nearing the end of my rope, here.

Every time I open up a certain scene in the Editor, after a minute or so everything will freeze up and become unusable. Often times, it seems to be brought about by my clicking and selecting objects in the Scene View, but if I leave the Editor open long enough it will happen regardless.

I’ve tried the Re-import All feature, but it did not help.

Interestingly, I was able to Select All the objects in the scene and copy them into a new scene, and it seems to work ok. However, this causes all of the prefabs to become permanently un-linked.

Is my scene file corrupted? What can I do?

Any help at all would be appreciated!

Thanks,
David

Forgot to mention - I’m using Windows Vista 32, and I’m on the Indie License.

Also, I just tried the scene again with the copied files, and that crashes as well.

Hm…it seems I’ve reached some sort of limit to the number of gameobjects you can have in the scene while the editor is running. The approximate number of gameobjects I currently have in my scene is 177. I’ve found that if I delete some of these objects, I’m able to work without the scene crashing.

It’s weird that Unity would have a limit like this. The performance during runtime and in the Editor (during the few moments where it works) is outstanding, so I don’t understand why Unity would arbitrarily crash once a certain number of game objects are in the scene.

Can you give a bit more detail about what is happening in the scene? Are the objects all of the same type, do they have scripts, are the objects’ meshes complicated…?
