Folks, An updated version of SDL Fractint has been uploaded to www.fractint.net. Fixes include: Fixed palette editor font. Fixed prompt/tab screen borders when a fractal type or formula has no parameters. Enabled orbits window. Fixed sound routines so emulation of PC speaker works and turns off when sound=no is used. Fixed functionality of orbitsave=yes/no/sound so that it will now turn off when orbitsave=no is used at the command prompt screen <G>. Note that I did not get the PC speaker emulation to reproduce the screech that you get in the DOS version when the orbit delay is too short. The sound skips, instead. The click due to the square wave cutting off when the note is ended is faithfully reproduced. The Advanced Sound Control features are not implemented.
