Multiple Subpanel Problems?

[Synaesthete]

In LabVIEW 2011, has anyone run in to problems using multiple sub-panels?  I'm considering an architecture that would benefit from having a couple sub-panels in a single VI, and opening sub-VIs in those panels that might also have sub-panels themselves.  I've heard that in past versions of LabVIEW this occasionally posed problems.  Before I go jumping in to it, have the bugs all been worked out in 2011?

I have an 8.6 app which has multiple subpanels, where some of those have their own nested subpanels and it works fine. I did actually give it a quick run in 2011 recently and it worked fine, but even without that test I would expect that there should be no problem with 2011.
