I frequently use QGIS to digitize satellite imagery or georeferenced maps. Recently, however, the Add Polygon Features and Add Line Features have stopped working - I can Add a Polygon Feature and trace the polygon, but QGIS will not respond to my right click which should finalize the trace and initialize the polygon feature.
Right-clicking (using control + , as this is a Macbook OS 10.13.6) works fine for other operations in QGIS, such as right clicking on a Layer to export, etc.
I have tried QGIS versions 3.4, 3.8, 3.10. And I have used every conceivable keyboard shortcut to see if it would register as a right click (command click, shift click, . click, etc). I have tried to find a way to change how QGIS interprets the keyboard, but I haven't found anything.
What's more, after trying long enough to 'close' the polygon, QGIS stops responding to the Esc key to exit polygon creation mode.
If anyone has encountered this issue, how did you resolve it?
