Hi JJMack,
Thank you so much for the idea about creating an action. That's a great idea! I'll definitely go that route!
And thank you also for the thought about the the resolution effecting the drop shadow size. I didn't know that. I think, though, that the resolution has been the same throughout. I'm doing screen captures using Snagit, so I think that the resolution of the images that I was using before the update to 2014 CC are the same as those I'm using now. So it seems to be working differently somehow. Maybe it's a bug?
Either way, though, you have given me a great workaround. Thank you so much!
Take care!
Mary
