GRAB.app - blank screenshots if using windowed mode.

[svkrzn]

One of the options of grap im trying to use is grab a WINDOW, after the screen is taken, it opens the preview but it's blank. White.

Actually i'm sticking with CMD+SHIFT+4+SPACEBAR, but wondering why it isn't working?

Are you clicking on the window after that?

Sure, anyway i solved that by rebooting my mac. Now it works.
