Earlier version was 1.5.6 (not sure)
Create a new cam, no go.
But...., I can reproduce the problem
When I use the overlay editor to create an overlay, nothing appears to the live view.
When I use the overlay / watermark option to create a watermark, nothing happens.
When I delete the overlay created by the overlay editor, the watermark appears.
When i insert an image or text with the overlay editor, everything dissapears.
I found out the problem. Insufficient rights to the path where the png files are.
Unchecked the read only box en voila everything works. Except the overlays I have deleted during test
Anyway, Thanks for your quick response Henrik, keep up the good work and have a nice day.
