Dear Developers, Have just upgraded to the latest release after a few niggles have opened my project and saved it under a new name this allows me to open it with out error meassages but the "strip locations" button on the "Peak list editor" window doesn't work any more and causes the following message. >> Exception in Tkinter callback Traceback (most recent call last): File "/home/bmbsjp/bin/ccpnmr/python2.4/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__ return self.func(*args) File "/usr/potato/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/EditPeakListPopup.py", line 250, in gotoOrthogStrips if self.window.stripAxis == 'y': File "/usr/potato/bmbsjp/bin/ccpnmr/ccpnmr1.0/python/memops/gui/BasePopup.py", line 389, in __getattr__ raise AttributeError, "%s instance has no attribute '%s'" % (self.__class__.__name__, name) AttributeError: EditPeakListPopup instance has no attribute 'window' The "go to position" button still works as does the "display strips" button in the "edit spin systems" pop up window (i had noticed that "display strips" worked significantly better than "strip locations" in the old release and was going to mention if it was still the case in the new release). I would be grateful if you could help me out with this as i tend to use the "strip locations" button quite a lot. Many thanks Stephen
