Dataset and rectangular upper limit stitching bugs

1)  ASC datasets mismatch with OPD when saving with Bad Data marked as NULL
a)  We took measurement with 5x turrent, 1x FOV of a 78rpm record. 
b)  As usual, top and bottom of grooves appear and sidewall information is missing.  We turned on data restore to see interpolated sidewalls.
c)  Save dataset as both ASC and OPD, the ASC dataset with Bad Data marked as NULL
d)  Close Vision
e)  Open Vision, and load ASC dataset
f)  The ASC dataset will differ from OPD.  OPD looks exactly like what we saved, while ASC is much different.  The interpolated regions and the successfully captured regions seem to be switched.  Note that this bug does not appear when Bad Data marked as NULL is unchecked

2)  Inability to do "Save As" from a loaded ASC dataset
a)  Once a new ASC dataset has been loaded, the File menu option for "Save Dataset As" disappears.  This is not the case with OPD datasets.

3)  Inability to save dataset with data restore interpolation

4)  Rectangular stitching crash due to area upper limit
a)  Set 50x turret, FOV 1x.  Rectangular stitching enabled for 156mmx156mm.  Any rectangular area bigger than this crashes, while area below does not.
b)  Take new measurement, Vision crashes without warning after taking first measurement.
