Pop-up window stuck in my Smarthub

[gianpyc]

Hi,
when I go to SmartHub, today my TV prompts me a window in which it say "Wait until expired APPs are deleted"
with a progress bar. But, after minutes and minutes the bar is stuck to zero and the pop-up doesn't disappear.
Moreover, the pop-up doesn't allow me to select the APPs the remains in the background without.

Do you know a way to remove this annoying window?

Thanks

Resolved,
I just switched off my TV, removed the usb-dongle that I use for the root, then switched on the TV again, I went to smart hub and the windows disappeared, so I switched off the Tv. Finally, I inserted the usb-dongle again, and switched on my tv and everything was ok.
