Versions prior to the 0.9.8 Sysnative BSOD Apps may have caused line spacing issues if you are using the $_header1, $_footer1, $_sig1, and $_driver_update_header1 files. You may have many more spaces between lines than you originally started with. The best way to fix the problem is to open the files themselves with the parms editor or a text editor and edit them so the line spacing is how you want it. Once the formatting is how you want it, you may begin to use the 0.9.8 version of the apps. The 0.9.8 version will continue to use those files, but the line spacing additions should now have been resolved.
You can also edit the line spacing through the apps interface, but it may not fix the line spacing as well as doing it through a text editor since it is difficult to see the formatting through the apps.
If you have the _jcgriff2_ app installed, the parms can be found under %userprofile%\_jcgriff2_\dbug\__jcgriff2_parms__
If you started with the Sysnative BSOD Apps 0.9.x version, the parms files will be under %userprofile%\SysnativeBSODApps\parms
