LabVIEW hung with "Resetting VI: Update VI Server with SL.vi" window

[Argonne_National_Lab]

I have a PXI-8175 with windows XP, LabVIEW 7.0, and LabVIEW FPGA 1.0, plus a PXI-7831R. Every time after I compile the VIs and try to exit LabVIEW, it is hung with a pop-up window says "Resetting VI: Update VI Server with SL.vi". I won't even be able to kill it through the windows task manager. The only way to resolve it is to hard reset the PXI. Any tips?

I have the same hang when exiting certain programs in LabVIEW.  I get a dialog box saying "Resetting VI: Update VI Server with SL.vi".  I can make it go away through task manager.  What does this dialog mean and how do I keep it from occurring?
