The problem with the data upload limit for attachments has been fixed. I have restored it to 30MegaBytes. A recent forum software upgrade was responsible for the changed limit. Please accept my apologies for missing this when upgrading the forum sofware, Mabula.
APP 1.074.1 OSX displays only an all black image after HSL Selective Color Adjustment
I am working with the trial version on Mac El Capitan.
The preceding tools worked well, and displayed the results properly.
After attempting to reduce the green level with the HSL Selective Color tool, the image display was all black. It does save the image correctly, but I cannot see the image on the APP screen to aid in adjusting the colors.
