Digital Light & Color

An update is available to Version 8.0.11 (20-Nov-2019)

The changes (taken from the update log) are:

Levels and Color Tool: fixed problem with mask overlay not being removed when clicking OK or Apply in some cases. Added a Mask Only button to the Mask Transparency tool bar.

Added a keyboard shortcut (Ctrl-R) to reload the last settings for the currently open transformation dialog box, if any.

Quick Pick: increased dialog box height to 90% of main window height.

Transformation dialog boxes that are left open are now automatically closed (by simulating a click on their OK button) when either selecting a new image, or when starting up a new transformation. Previously, recalc would stop when reaching an image whose transformation dialog box was open, even if it was currently hidden.

Clone: enabled split screen display in the case of no source image specified.

This behaviour can get you by surprise with the Print transformation as it simply starts printing process without your explicit wanting.

I was editing margins to place the image assymetrically in the Print dialog and at one moment I wanted to check one of the transformations upstream. Of course this started the printing process.
It gave me quite a start as I was about to print A2 format and was not sure whether I had got the margins and other settings right.
Fortunatelly everythig turned out all right.

Now I am not sure whether the Print transformation (or perhaps any transformation) should be executed without the explicit click on the OK buton. You can take back effects of all transformations, but not a running print.
In my opinion, clicking on or starting a transformation while you have another one still open equals to abandoning and cancelling it, not confirming it.

But others may disagree.

That was an unintended consequence. Probably the same issue with Export.
