As a very long-time registered user of Screenshot Captor, I do remember a time when this feature worked consistently well. But it's been a long, long time since then.
(Btw, as I recall, back when it used to work, it seemed to do more flashing and back-n-forth scrolling than the competing programs like SnagIt. But that was no big deal because it always produced a full image in the end.)
Anyhow, I just tried an auto-scrolling capture of a simple webpage in Firefox 11, and it failed to work on TWO LEVELS:
As I understand it, I'm supposed to press Ctrl+Shift+PrintScreen AND THEN Ctrl+Shift+click.
I definitely remember in the past -- when this feature worked -- the first keyboard command (or tray menu command) resulted in a red-lined frame around the webpage. This appeared with little or no mousing on my part.
But that red-lined frame no longer appears around the webpage. It appears as just redline toward the bottom of the webpage. And if move my mouse toward the system tray, then partially-obscured red instructions appear.
(I tried to get the frame to surround the webpage, by using my mouse like I would for a custom selection screen capture, but it didn't work. And besides, I shouldn't even have to do that. After all, it's a windows object or scrolling capture, so screen capture should know what needs outlining with the red-lined capture frame or box.)
Nonetheless, I thought I'd try the second step: Ctrl+Shift+click.
Thankfully, I'm not susceptible to seizures from strobe lights, or what ensued might very well have triggered convulsions. The flashing was extremely rapid, and it appeared to be both endless and pointless. Finally, I clicked the escape key, and here, I'm happy to say, the program worked. It stopped attempting the capture.
I was a bit worried I'd have to restart my PC, because the graphics were only partially displayed. But with a bit of minimizing and maximizing of windows, all returned to normal.
Enough said. PLEASE, Mouser, fix this feature. Otherwise people will certainly move to other program for screen captures. And I don't want to do that myself. But at least for now, for scrolling captures, I must do that.
PS: I was just trying to capture www.abookapart.com
-- there's no flash on the page, and nothing fancy at all. (It was just for a little collection of webpages with exemplary designs or at least some exemplary design elements.)
CLEARLY, the feature fails right at the beginning.
