Icon Editor Bug (2010): Using icon editor degrades sub vi performance

[Daklu]

Here's an interesting bug I've spent the last several days chasing around.

After editing a vi icon calls to that sub vi take longer until you close the project and reopen it.  I think it's related data copies being made for instances the IE opens, but without any knowledge of IE internals I'm just speculating.

See the Main.vi block diagram in the attached project for repro steps.

Confirmed (LV PDS 2010).

Thanks Chris.  (Several Lava users confirmed the repro here.)

Update:  I don't think this is a bug in the IE.  I have observed the performance reduction in situations where the icon editor hasn't been used, but I haven't been able to identify other specific actions that cause that effect.  The icon editor is simply the easiest way to reliably repro the problem.
