I do not know how it is possible, but your header mentions Pharo 6.1, but according to the UI you have Pharo 7. And the missing class is part of Pharo 6 only and is not required in Pharo 7. One reason might be that you keep locally old (2 months) GToolkit code. Can you check this? Juraj -- Juraj Kubelka El 29-09-2018, a la(s) 14:37, Hilaire <hilaire@drgeo.eu> escribió:
Indeed new VM passed that error. I have another issue related to unmet dependencies. See screenshot.
Not sure it belongs to GToolkit or P7.

The current Pharo 6 & 7 VMs are both dated 28 June 2018.
