Hello all,

I run CcpNmr Analysis Version 2.4. Release 2. I have updated my computer from Ubuntu 16.04 to Ubuntu 18.04, and Analysis started behaving oddly. It seems to hang randomly when opening new windows (both dialogs and spectra), and (sometimes) recovers when typing ^C on the terminal, giving this kind of output.

^CKeyboardInterrupt: 
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/memops/editor/OpenProjectPopup.py", line 208, in apply
    self.callback(self.project)
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/analysis/AnalysisPopup.py", line 1664, in initProject
    self.openActivePopups()
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/analysis/AnalysisPopup.py", line 872, in openActivePopups
    func()
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/analysis/AnalysisPopup.py", line 2778, in runFormatConverter
    popup = self.openPopup('run_format_converter', FormatConverter, project=self.project, oldStyle=True, threading=threading)
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/analysis/AnalysisPopup.py", line 1824, in openPopup
    popup = self.popups[popup_name] = clazz(self, transient=transient, *args, **kw)
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/format/gui/FormatConverter.py", line 190, in __init__

  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/memops/gui/BasePopup.py", line 128, in __init__
    self.initial_focus = self.body(frame)
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/format/gui/FormatConverter.py", line 222, in body
    self.initProject(project = self.project)
  File "/home/fito/bin/ccpnmr/ccpnmr2.4/python/ccpnmr/format/gui/FormatConverter.py", line 654, in initProject
    self.update()
  File "/home/fito/bin/ccpnmr/python2.7/lib/python2.7/lib-tk/Tkinter.py", line 1015, in update
    self.tk.call('update')

I couldn't find any report/solution on this kind of problems neither in this mail list nor on the web. Any idea on what the problem could be and how to solve it?

Thank you in advance

Fito
