When i turned on a vpn app to then use an iptv app and then when finished with the iptv and turned off the vpn, none of the on demand apps (iplayer, my5 etc) would work.

Clicking an on demand app appeared to open it but all i would get was a black screen. Hitting the android home button would get me back to the apps home page, but if i tried again or chose a different on demand app i would still get a black screen.

Rebooting the device was the only way to get the demand apps working again.

Anyone else seen this?
