Flashaudio no longer available for Radio 4?

[Jeremy Bartle]

When I tried to download some BBC Radio 7 and BBC Radio 4 programmes
today using flashaudio mode, the BBC 7 ones worked as normal, but the
BBC Radio 4 programmes were not found using this mode.  I eventually
downloaded them using flashaacstd1, which is inconvenient as I then
had to convert them to MP3.  Has anyone else had this problem?
