This topic came up in the Premiere Pro forum and I am experiencing the same behavior with my IOxt. When working with Premiere Pro, the AJA control panel indicates that it is in use by PremierePro but when I switch to After effects the IOxt does not follow the app and continues to be in use by Premiere Pro instead of following the switch to AE. The only way I can force the Control Panel to switch to AE is to quit PrPro.
I think I remember this working at one point in time but it does not now. Both the PrPro sequence and the AE comp are the same frame rate and resolution.
Anyone have any ideas on how to force the control panel to follow the active application?

It sounds to me like a Mercury Transmit issue. I don't actually think that AE supports Mercury Transmit like Premiere, Prelude, and Encore do. These applications will automatically follow you when you switch between them but I don't think AE does. I could be wrong but I couldn't find anything about AE actually having this support.
