If you are using auto recording, then I would suggest turning
it off and using PrntScr to capture your screenshots. If you are
already doing this then capture the problem screen manually outside
Captivate and paste it on to a blank slide as a background, then
build in your captions, mouse, click boxes etc as needed.
I forgot to mention that I can record the site fine on my
laptop which is also connected to our network, but only encouter
the problem on the desktop. I compared the settings and everything
was the same....
