   I've implemented screen capture in my program as discussed http://groups.google.com/group/cocos2d-iphone-discuss/browse_thread/thread/3e62da7f3c32385d/f6b9bcfdcd5740bc .
   The problem is I want to remove a meny before I capture the actuall screen, doing somthing like this;
   [menu setPosition:cpv(-30,280)];

   This seem to work ok when done outside of the screen capture function, I guess the update of the menu isn't done when I start grabbing pixels from the screen.

   So my question is if there is a way to force an update of the screen somehow (through the director?) or a way to wait for the update to happen?

   Regards Fredrik

   Could you add a slight delay after hiding the menu, but before taking the screen shot? It might help...

   My guess is that you should wait until the next frame: the menuitem
   that triggers the screen capture (or the way you do the screen
   capture) might set a variable that will be checked in a scheduled
   method, if that variable is set, that means that the next frame needs
   to be captured, then reset the variable and reposition the menu. I
   would do something like this (pseudocode):

   
menuaction:
grabScreen = 1

   tick:
if grabScreen == 1
# this will be probably in the same frame as the menu action
grabScreen = 2
else if grabScreen == 2
# now we're for sure in the next frame
captureScreen()
grabScreen = 0 // reset
repositionMenu()
end

   Thanks for the help though I still feel a little stuck...
   I tried to use sleep and NSThread sleepForTimeInterval, both locked the application for the specified time and no update happened to the graphics during the time (screenshot eventually happened but still with menu).
   I Also tried with a scheduler but only got a black screenshoot (or as I changed GLClearColor I could get a completly green screenshot) as the Director clear the screen right before it runs any scheduled methods.

   I'm a complete noob when it comes to Mac/iPhone development so I'm sorry if I don't explain good enough.
