I'm a couple of versions back. (4.85)
Remember that cute little trick you put in for me a big while back, where "1 click" on the tray icon initiated the capture rectangle?
For a long time (but I never really worried about it) I have noticed a lag, maybe as much as 3 seconds, before the rectangle capture would kick in. But quasi recently I've been doing more capturing off videos, where the video (be it TV/movie or Youtube) shows something for under a second but I want to gaze at it idly for a week on a Sticky (Tom Revell / Zhorn).
But in videos, that 3 second delay means when I click the icon, 3 seconds later, that quick flash image is no longer there!
So I have to back up like 3-7 times, remember the trigger points, and guess when to click, and hope that when the rectangle locks in, is the image I want.
Was that lag a function of the ugly hack you needed back in the day for the feature, or do you think it's easy to clean up?
