You can stop the rotation by clicking in the space again."},

selected, windows will be created with a fixed size and automatically staggered. \
If Manual is selected, you will need to drag out the outline of new windows \
before they appear on the screen."},
{"DRAWMOVING", "Interactive Drawing", PT_AFFINT,
"This controls how visualization objects are drawn when you are interactively \
changing them. If Full Quality is selected, objects will always be drawn in full \
quality. If Faster is selected, objects will be drawn with only a skeleton while you are \
interactively moving them, which is much faster. This can provide better feedback \
on slower computers. If Automatic is selected, SciAn will automatically choose whether \
objects are to be drawn fully or faster depending on how much time they take to draw."},

the vertical position of the icons will be staggered so that long icon names have \
less chance of overlapping. If No is selected, icons will not be staggered."}

If PostScript is selected they will be saved as embedded PostScript files with a file extension \
of .eps. If IRIS RGB is selected, they will be saved as IRIS RGB files with a file \
extension of .rgb. Screen saving is done using the recorder drivers, and the \
parameters are set within the recorder driver control panels."},
{"IDLENAP", "Nap When Idle", PT_YNBOOL,
"This controls whether SciAn naps when it is idle. When No is checked, SciAn will \
constantly run housekeeping functions. This will ensure that interaction is quick, but \
it may slow down other processes running on the computer. When Yes is checked, SciAn will \
nap for one-second intervals five seconds after the last window change. This will \
release time for use by other processes, but the first interaction when it is napping \
may take up to a second to respond."},

faster."}
