Strange object keeps crashing scene?

[Jorbu]

OK, I've never experienced this before. My scene keeps getting this strange object which has no name and if I simply click on it to try and delete it, MAX just crashes. Also, when I re-open the scene I get an error message and after I press OK, it continues to load and tells me that objects in the scene were saved in a previous version of MAX.

 

I haven't figured out where this object comes from? I can merge my objects into a new scene and get it so it's not there anymore, but eventually it shows up again and I don't know why.

 

About my scene, it is rather large, for that reason I have vray proxies for the surrounding buildings and the tower mullions(2.8 million polys for the mullions alone), also I have one x-ref scene which has 1.2 million polys.

 

I'm using Max 9 with service pack 1 and vray 1.5

 

Any ideas what this is, how to get rid of it and how to keep it from showing up again?
