Quote: In 4.62 IrfanView introduced a new option, which is enabled by default: Options -> Properties/Settings -> Viewing -> Apply PNG/TIF/TGA/DDS/EPS/RAW (or Edit->Paste) alpha transparent color
This combines a clipboard pasted 32BPP image coming with an Alpha channel with the window color.
If this option is disabled, pasting works.
