Can anyone tell me why I get this error with the following code? It is a snippet from a larger app that uses copy image acquisition buffer to display multiple images in a while loop. I extracted the offending code and I still get the error so it is isolated to the copy image acquisition buffer vi which kicks out a "cannot resize image in an acquisition buffer" error. A similar application I have written works fine, so I know the methodology is sound, but the IMAQ version is older in the other app (3.1) and I used IMAQ copy instead which is now deprecated in 3.8.
