Dragging part to new assembly issue

I have a large assembly that I am trying to organize better.Some of the parts in the root of the assembly should really be inone of the existing sub assemblies. No problem here, because I canjust drag it into the sub assembly.

However, I also have a few parts in a sub assembly that reallyshould be at the top level because of the way I want the model tomove. The problem is that if I attempt to drag it to another spot,it will always go into the other sub assembly. I tried dragging tothe very top of the tree, but my icon shows that I can't do that.

The online help says that SW distinguishes between dragging a partinto, verses after an existing sub assembly, by if the 2nd subassembly is expanded or not. However, regardless of if the 2nd subassembly is expanded or not, the part always goes into that subassembly.

Is something wrong with the current release of SW in this function?
