Bad Touch - frozen touch panel

[vova]

The touch panel of my x1060 freezes after I transfer some like 8GB of music (ca. 1200 files). Buttons works, but touch panel doesn't react. All seams to be fine while there's way less files (no problem with few albums). Most of my files are aac 256 or 320kbps, but still plenty of mp3 and vary bps. No pictures, no videos. Reset doesn't help. I formatted twice, uploading similar amount of files. After formatting everything works for few a while (some time of playing music), then again, no reaction to a touch. I'm a Mac user (for 20 years: walkman is Sony, computer is Mac ), but there never been any problem with previous walkmans (same set of music works perfect on S738).
Any suggestions what's going on, please?
