It seems to work fine. I wanted PNG support, so I downloaded the PNG library from ezwinports. I installed it so that the /bin directory is on the path. I've done this before. I'm fairly sure that last time once I'd done that PNG support just started working. PNG support doesn't seem to work though. It gives the error "Cannot Display Image: (Invalid Image Specification". I noticed one thing that might be the problem. I used the 64-bit build of Emacs. But, ezwinports only has the 32-bit build of the PNG library. I don't know if Windows can deal with a call from a 64-bit program to a 32-bit library. If it can't, where can I get a 64-bit version of the PNG library? BR, Robert Thorpe
