Confirmed on both a 50g and 49g+ running 2.15.

I think I recall seeing a list of bugs fixed in 2.15 but can't find it now. Perhaps I'm mistaken about that, but I do know at that stage, HP was only patching the 50g ROM if absolutely necessary (as there was literally no free ROM space left, so every single change took lots of work) so I'm fairly sure the 2.15 release was driven by bug fixes, even if they weren't acknowledged in public docs.
