Attempting to use the trial on a Macbook Pro with NEC PA 271 monitor connected. Can't get ASP-3 to exist on, or be dragged over to, the large 2nd monitor.
Apparently, based on comments I saw in Corel's user forum, ASP-2 did not support multiple monitors. Interestingly, ASP-1 works fine on two monitors.
Oh well, that was a quick trial....
UPDATE: In the interest of fairness, I learned that by mirroring the two available monitors, and then selecting 'full screen', one can operate ASP-3 on a second monitor, although the #1 monitor(the laptop screen, in my case) is now occupied with a small image of the same thing. The absence of the freedom to move and position the overall window is annoying, however. Many complain about the inability of Lightroom to detach/reposition the control panels, but this is worse IMO.
I can report is that:
1) The ability to recover highlights seems to be weaker than Lightroom in terms of range.. It reminds me a lot of Lightroom/ACR Process 2010, which, depending on what you're trying to do, could be a good thing. Except, ACR/LR already has Process 2010, AND Process 2012.
2) It has a really thin "print module" of sorts, but it's not nearly as feature-rich as Lightroom.
3) It crashed a lot. I manage to make Lightroom crash about 2 or 3 times a year. ASP-3 crashed several times in half an hour.
