I've set up macros with IR and page jumps in, so you aren't trying to do anything it can't handle. I've tended to do the page jump first when doing a 'please wait' page, but I don't think that should make any difference. I'd try putting a very small delay between the commands themselves and the first page jump, as sometimes asking it to do two things simultaneously doesn't always have the desired result. I also always put a very small delay between commands for the same reason when asking a button or macro to execute a series of things.

I hope that this works for you!
