Performance issue with editing classes in 2011

Question

Maybe this is just an install issue, but....
In LV 2011, if I attempt to edit the data of an established class (i.e. it has accessors, etc) then I get the Windows 7 whirling cursor indicating that the class is updating; sometimes this takes several minutes for the changes to be applied while other times the system just hangs and I eventually have to kill LV thus creating a hideously time wasting cycle in where I once again attempt to make changes to the class, it hangs, ad infinitum.  Has anyone else seen this?  Is there a work around?

No.  I am saying that this is not associated with a project.  A class does not have to be associated with a project.  If you open a .lvclass file you will get a window that looks like a library window where, similar to the library, everything contained in the class namespace will be found.
I am running LV 2011 on a 32-bit Windows 7 machine with a dual core i5 (2.53 GHz) and 4 Gb of ram.  Performance wise, I am having no issues with any other aspects of LV 2011 (strike that - it does seem to crash more than I desire).  As I said in the above post, this seems to be an issue only when I am trying to change things such as names in a space other than the properties dialog box. 
I suspect this might be associated with the installation, but I am not positive.  I have attached two classes if you are interested in playing with them.  Basically, I was only trying to change the type and name of the variable tscan in the SMPS class (I included the CPC class due to the dependency of the SMPS, but I am afraid there may be some other dependencies that I can not immediately see).
