@NiLuJe
Resigned an account in order to discuss some problem with your screen saver and the fonts hacks(I haven't tried the latter but most of the non-English forums they have reported that it goes wrong in KPW3.)
And mine is the same.When i tried to use my own paper to change the screensaver of my KPW3 and it appears just like running the Sleep mode.Or with a whole gray screen sometimes.
The resolution and detail of the PNG i have converted by PhotoShop.Does it have any problems?(In PNG-8 256c or 16c or 8c all failed.And when i restart the frameworks.The Photo which the "Hack" embedded doesn't work.With the USBNET unplugged.)
Or could you send me a detail of the Photo Resolutions?.
Having tried again and again.So please take it seriously.
