Found the email address. Just in case anyone is interested, here is the issue:
I have a link to a screen movie showing the problem, below.
I corresponded with someone at Pixel Genius about a year or so ago, when -all three- of the packages quit working for me. At the time, support gave up. I pressed on however, and today I made a screen recording of what happens in about 1/3 of a second when launching the software. This happens in both PS CC 2015 and in a fresh install of PS CS6 which I did today.
Something that resides in the system, or in Adobe's files, is preventing the software from working. This example has been made with 1) a completely new user and 2) a completely fresh install of Photoshop CS6, as well as a fresh install of Photo Kit Sharpener, (PKS).
Here's what I see when stepping thru the screen movie frame by frame:
open an image, and invoke PKS.
a window named Photokit Preview zooms open from the center of the screen. Based on 30 FPS, this takes 5 frames, or 1/6 of a second.
It then disappears, and is replaced with a tiny window, about 100 x 120, filled with black, and also named PhotoKit Preview. This window remains in place while
behind the small black window, the full PKS dialog opens ( I never saw this before taking the screen movie today, but that's because...) it lasts only 1/10 of a second, and then it, and the black window both disappear. (Without using screen recording, this just looked to my eyes like "a flash" and the black window disappearing. Also, the PKS window appears -behind- the image, so I never saw it for that reason as well. This time I repeated the filmed launch, and moved the image out of the way.)
So: there's a detailed description of an event that takes 2/3 of a second to happen in full.
Again, this is with
1) a new user
2) a new install of Photoshop CS6
3) a new install PKS.
I've posted the movie here:
http://transfer.pronet.link/transfers/screenmovie.mp4the event starts at 9:19 (9 seconds and 19 frames in), and ends at 10:02 (10 seconds and 2 frames. I suggest stepping thru that period, one frame at a time.)
I'm running 10.11.3, although this happened back in Yosemite too.
I suspect that the window position recorded in the user system database cache is corrupt, but I have no idea where that might be (well: probably hidden in /private/var/folders/, I’d guess, or somewhere similar) much less how to delete it and start anew.
I'd very much like to try to resolve this, as I've been without Pixel Genius' excellent software for over a year now, not to mention being out the $250 I spent on it.
(The Photokits are up to date, and were downloaded yesterday. As a retired programmer, I've done everything I can think of, culminating in what simply ought to work, regardless: new user, new PS install; new PK install. But nothing changes.)
Suggestions and/or sage council is welcomed.
Thank you.
