Arrows from Metro interface became rectangle h ttp://img405.imageshack.us/img405/4/77034866.png The "mute" icon also the same ht tp://img526.imageshack.us/img526/9408/16618051.png after 2,3 days of use.
I noticed that with the lite-version of Nil: you probable use that version. But this is a bug in that Windows right from the start and not after 2 or 3 days.
I used "Microsoft Windows 8 RTM (Core, Enterprise) x86/x64 (Original ISO) [MSDN] [English]". And it's not a bug from start 100% I used Refresh option from win 8 and everything came back to normal, I'm pretty sure this will come back after few days.
That might be the case. In stead of the arrows up and down it shows a character with a hand, holding a pencil like this: . It looks like that Windows-version is missing a certain font. I compared the fonts in the Nil-version with the regular version, and there are two Wingding-fonts that are lacking in the Nil-version: WINGDNG2.TTF and WINGDNG3.TTF. I copied both, and will restart in the Nil-version to look if this makes any difference.
I forgot that I removed the lite-RTM-Nil-version for the lite-RP-version, that hasn't Metro at all! So I can't check it; maybe some other will?
