What steps will reproduce the problem?

2.Save file or load file
3. Takes a long time to do this

What is the expected output? What do you see instead?
Takes a long time to do this.  If I pause the graph, the operation behaves as 
expected in a normal time frame.  

What version of the product are you using? On what operating system?
I am using WinGui 2.2 and OS is Windows 7.

Please provide any additional information below.
Perhaps you could pause the graph during the load and save operations. Or at 
least put up a message to pause the graph during those operations.
