When I try to take a screen clip with CMD-SHIFT-4 the OS goes through the motions of letting me draw a clipping box around what I want, and when I finish the screen clip, the shutter sound plays as if a screenshot was captured, but no screenshot is saved to the desktop.
When trying to do a screen record using Quicktime, I can go through the motions of setting up the area I want to record, but once I start recording the record controls disappear. After that, I cannot start a new recording because Quicktime acts like it is still currently recording (no file is being create that I could see).
Thanks for the help by the way, let me know whatever the mechanisms we have here for reciprocity.
