Folks, I've updated the SDL port to not crash as often when changing image sizes. The Windows version sometimes provides a blank screen because it thinks the parameters have changed. Toggling the <F> key (floating point) will get the image to generate. The mouse zoom box behaves a little differently in that it will now change size in the direction the mouse is moving. I am working on a 64-bit Windows version, but it doesn't want to link. Windows version (32-bit) is: https://fractint.net/ftp/experimental/SDL2-fractint-20.05alpha-2017-10- 15.zip Pre-compiled 64-bit Linux version is: http://www.fractint.net/ftp/experimental/SDL2-Xfractint-20.05alpha-2017 -10-15.tar.gz or look in the directory: https://fractint.net/ftp/experimental/ Jonathan
