We are having same problem with Silverlight. It does not even recognize the first step when I try record it ask for a question regarding requiring additional storage space in order to operate correctly and click okay. Then silverlight in pop up window and ask "Do you want to increase available storage?" and I click yes. WPM does not retain any of these actions and i cannot pass the point. I asked for enhancement request after working with support that was about 6+ months ago.
And we have some other transaction what we need to monitor XML, but WPM does not handle either.
