Save 'Layer' not working/save 'Layer' dialogue box missing

Hi. I’ve not been able to save a layer in backbone. A very brief flash of a window outline pops up and then disappears which I take should have been the dialogue box. This issue seems to effect both Windows and Mac. Tested on both operating systems using Ableton as well as Cubase -the issue persists. I have inspected my user ‘Layer’ folder (which should be the default location for saved layers) but it is empty, so even selecting ‘Save’ in the layer drop down doesn’t work either. Is anyone else having these issues?
