More likely no one else have this problem
Maybe you could give more info: what firmware are you using, are those folders on internal hdd, network shares, usb? Or upload some pictures you're using for icon mode so we can try them, maybe they're the cause you never know... (just throwing ideas in the air)
I remember having lots of problem with icon mode back then with older netshare 2.01 along with tvix firmware 1.1.x (instability mostly)
Starting with firmware branch 1.2.x and netshare 2.02 all these problems were solved (at least for me)
