I have the same problem. If you resize the layer window your layers will reappear.
I tried re-sizing, moving to my second monitor and docking. Still blank.
hmm... it worked for me...
Try changing the filter, then change it back. That should refresh the list.
See the screenshot
I have tried every filter and every other button on the layer list toolbar with no luck.
Do you have any layers showing up on the status bar?
Hi Dan(s)- right click in the column header and check the columns you want to show- somehow, and it would be good to know how, all of these got turned off. Did this work and then suddenly show up like this out of the blue, or is this a new installation, or?
