Okay to drag window while imaging?

[natevw]

I noticed at least on Windows 7 that if I move the SCP app window around while imaging a disk, the process gets paused while I am dragging. As in, while I am dragging the window and my mouse is down the drive noises stop and the orange squares stop filling in.

Is this harmful and do I need to avoid moving the window while it is at work? Will the pause in imaging corrupt the image files in any way?
