I've found where comes the problem : .tga files are effectivly not always well rendered with WIN98 2nd, so i use to convert them to .bmp ... BUT, translucent is usual used with .tga's (am i right to say that equivalent code is "perpixel=1" ??) and it's absolutly necessary to hold it off if converting in .bmp's. With this condition i've succeed to make skins which did'nt work (or which had getting troubles with none skinning buttons more exactly ...) now work with WB 4.20.017.
Anyway, i'm still sad to have lost the possibility of having an explorer background
, (and still wonder what WB4 brings exactly more than WB 3.51.053 ... but for this point i'm probably missing something 'cause of "english using" in options ...)
