Normally, SC works great. It even works well for a lot of auto-scroll captures too. I still get the ugly flashing black regions, but everything is restored after the capture. However sometimes, and this bit me again today, it looks like it's going through the auto-scroll motions as it should, but the resulting capture is incorrect.
Today, I had reason to capture an image of my Spam folder view from GMail. At first I thought it captured fine, but then looked closer and noticed otherwise. After several attempts, I would always get one of two results: either it would only capture the visible region and not the hidden region, or it captured the visible portion of the region, and the bottom few hundred pixels, but everything in between was missing. To illustrate this latter case with some crude text, given a scrolling region laid out like so (with the bold lines being visible, the rest scrolled out of view):AAAAA
what I get when i capture is something like
Make sense? I suppose I could work up a graphic or post the actual screenshot, but I figured that would get the point across.
BTW I tried it in both IE7 and FF3, running XP Pro SP3. I also tried starting the capture from the bottom and middle of the scroll region. Starting at the top usually resulted in only the top visible region captured. Starting at bottom or middle gave the result with the middle content missing.EDIT:
Slight correction and clarification: upon further examination, it always captures some
of the very bottom of the region. When I start the capture from the top of the region, it includes maybe the bottom 200 pixels (rough estimate) of the scroll region. When starting at the bottom or middle, it captures maybe twice as much from the bottom, perhaps 400 pixels. This is at a total vertical resolution of 1200 pixels. In both cases everything between that and the topmost portion is missing.
