The icons for the adjustment layers are missing in the adjustment panel in photoshop. I am on PS version 24.7. I updated PS last 23 days ago. This just started happening today. I have shut down and restarted photoshop and it does not correct the issue. I checked the "Window" menu and "Adjustments" is checked. I can go to Layer -> New Adjustment Layer and add adjustment layers, but this isn't as convenient as clicking on the icons in the panel above the layers.
Dag, ISTR more people were losing toolbar icons than Adjustment layer icons. For me it was the same as the OP, but I am not seeing the problem any more with both full release and beta versions.. I am on 24.7 and 25.1
