Let me just confess that I have such a multi-faceted life these days that I spend little time on fractint, probably less than most people on this list. But today I'm home from work early and have a little time so I rediscovered some work I did late last year. On my Windows 7 64 bit system, I have the DOS fractint in c:\fractint. I have two versions of DOSBOX, the official one 0.64, and an enhanced "svn" version, that is both built off a non-released DOSBOX subversion code modified with unofficial features. The "SVN" DOSBOX looks to be far better than the official one for our purposes. Here's where I got DOSBOX: http://ykhwong.x-y.net/xe/dosbox_data/143 And download the 7-zip file in the blue box: 20120220.7z Unpack this into a directory of your choice. I edited the file dosbox.conf, and added some lines on the bottom to make my fractint directory visible (modify to match your fractint setup): [autoexec] # Lines in this section will be run at startup. # You can put your MOUNT lines here. mount c c:\fractint c: fractint Then just execute from a file manager: dosbox.exe and Fractint comes up. What I love is that the high resolution modes work in this DOSBOX version. They don't seem to in the stock release. I edited the SF10 mode in fractint.cfg like this to get 1600x1200: SF10,VESA Standard interface ,4f02, 120, 0, 0, 28, 1600, 1200,256, DOSBOX Even color cycling works! I'd be curious to know how others are doing under Windows 7. Tim
