    no bug When browsing images with transparency in fullscreen - background go to black

    If Irfanview (4.42 32/64bit) work in fullscreen mode and Main window color si changed i.e.: orange, if browse image in fullscreen mode, background change to black.


    Details:
    1.) Set main background color:
    Options-Properties/Settings-Viewing-Main window color: set any bright color (orange, bright green... etc.)

    2.) Copy more images into one (for testing empty) directory
    i.e. this two images (or the same image with another name):

    Click image for larger version

    8-bit transparency (open image and save)
    Click image for larger version

Name:	TransparencyTest1bit.png

    1-bit transparency (open image and save)

    3.) View this image into IrfanView in fullscreen mode
    Transparent background has set color

    4.) Still in fullscreen and browse next image
    Transparent color is now black - change previous image or go into window mode - background still black

    When browse image in window mode (next-previous), background color has ben repaired to settings value.

    Change the Fullscreen Window colour from black to whatever you wish in Settings, Fullscreen, Screen colour, Choose...

    I tested by setting my window colour to yellow and my (fullscreen) screen colour to blue) then I browsed a folder of program icons with transparency.

      Thanks, but in these situation bug is: change window to fullscreen (and vice versa) - background color not changed (until image not changed).
