But hey, new problem

While positioning the icons of the mainmenu buttons, I noticed there's a bug in handling some transparent PNGs which causes the icons to be a bit bigger and shifted to the right and bottom... quite a weird problem


Left: with background, right without. (Left is exactly the same picture, only saved with a white matte). The left one has the correct placement.
The procedure was quite simple: I took the media icon from the Onyx WS skin and just resized it to 128x128 and saved it with Photoshop (which should make it the exact same file format as it was). The version with background was saved through 'save for web' in Photoshop with a white matte. Next I saved a transparent version through 'save for web' and that one just works as it should! Apparently there's a difference between those two, I just can't find it (they're both PNG-32 while the version with background is PNG-24).
For those interested, I've put the three icons in a
RAR.
Anyway, I'm going to resave all the icons with 'save for web'.
(Yes, I know I shouldn't be using the Onyx icons for my own skin, but they're a temporary solution... wanna get the basic skin working before designing new icons (and dialogs and other screens and... pff

))
Also the scaling problem is still present:

(Onyx WS Night skin in 1024x768 sometimes gets a blue line around - usually - the play/pause button)
