I am having an issue SW2012 that was never present for me in previous versions.  Whenever I edit a dimension within the context of an assembly it takes a long time for soldiworks to allow me to edit the values in the "modify" text box. 

This happens when I edit a dimension for a part and when I edit a dimension in a sketch that resides within an assembly file.  The lag time varies depending on how "deep"  the dimension is within the assembly (ie the lag is longer if I edit a part that is 3 sub assemblies deep than one that is only 1 sub assembly deep).  This lag time can vary from 10 seconds to almost a minute.  As you can imagine; this is very frustrating if you are used to working at a faster pace.

Here is what happens in order of events:

1.) I double click on a dimension that I wish to edit

2.) The "modify" text box pops up immediatly

3.) Once I click on the box or try to key in a value; I get the Windows 7 blue calculating circle until Solidworks decideds it will enter my value (this is the new lag time).

4.) I press enter to accept new value and the change happens immediatly after I hit "rebuild"

Other strange observaitions:

1.)  I don't have this issue if the quick input box (the box that only has a value field with no stated units nor config/link values settings).  However, I can't seem to get this input box to appear when I want it too.

2.) If I have a reference sketch inside the top level assembly file of a large assembly; editing these dimension will take over a minute.  This is even if there is nothing yet mated or refenced to them.

3.) During the lag time I can key in my entire value input and it will appear complete once solidworks is done calculating.

Has anyone else experianced this problem?  Any input would be greatly appreciated!
