Question

Windows

sticks to messages from the disk, sometimes from OPERA, and from other notifications and as a result - search is not available and the restart button from the

Google tiled screen is still silent - maybe I'm just asking the wrong question

Answer 2

portable usb hdd. in fact, notification sticking also happens when using the opera - I use the hashmem.com service to save bookmarks - when a new bookmark is created, a new notification pops up. in 70% of cases, everything is fine, but after a time or two, the freeze also happens.
