How do I load a PNG file with alpha channel?

BlitzMax Forums/BlitzMax Beginners Area/How do I load a PNG file with alpha channel?

Additional information from my experiments:

- "dividers" appear under MacOSX, as soon as I "createPanel" without any border request
- sometimes, .bmp images appear properly under Linux (and I'm always talking about the same .bmp file!)

Thus, the most important question which remains is: how do I get transparent PNG images under Win32 and Linux?
