Grab Active window saves black body when the active browser is IE9 and maximized

[jiying]

I'm using Windows 7 Professional SP1 x64, with screenshot captor installled, it works great, but the "Grab Active window" feature seems have an issue, it saves the IE9 browser window with black content, please see the attached screenshot. I believe it happens when the IE9 browser window is maximized.

Given the fact that it's only the interior thats black, i wonder if its an artifact of not having enough time to refresh the content during the active window transparency trick.

To see if i'm right, try doubling this value or making it even higher:

It seems not the cause. I changed this setting to 4000, but still get the same.

... the active window transparency trick.

Why would he need that? It's in Windows Classic mode what he shot.

Well if he is using classic mode without border transparency, an easier fix is to complete UNCHECK the "Try to capture Aero Glass.." checkbox at the top of that options tab.

Thanks! The real cause is the "Do not try to use the PrintWindow() API to grab non-aero windows". I should check it.

How interesting.. I don't remember that option ever being useful and it was added many years ago.  I wonder if anyone else has ever experienced a similar issue with it. Perhaps I'll go have another look at the code and see what purpose it serves.
