Hi I get the following traceback when I try to print a window to an "other" page size. I've tried various formats for entering the page dimensions, but always the same. Just a problem with the unit selector? Exception in Tkinter callback Traceback (most recent call last): File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__ return self.func(*args) File "/usr/local/ccpnmr1.0.13/ccpnmr1.0/python/ccpnmr/analysis/PrintWindowPopup.py", line 115, in saveFile self.updateAppData() File "/usr/local/ccpnmr1.0.13/ccpnmr1.0/python/ccpnmr/analysis/PrintWindowPopup.py", line 109, in updateAppData self.print_frame.updateAppData() File "/usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/gui/PrintFrame.py", line 333, in updateAppData other_unit = self.other_unit.getSelected() AttributeError: 'NoneType' object has no attribute 'getSelected' -- Dr. Brian O.
