[Plugin: BuddyPress Mobile] Not switching to default mobile theme when used with certain wp themes

I know this plugin isn’t supported by the developer but I am hoping that someone knows the answer to this problem:

BPM isn’t switching to use its default mobile theme. It still uses my theme to display the BP pages on the iphone. I use ‘the morning after’, and I have read where people have the same problem with ‘scholar’ and ‘salutation’ themes.
