Compatibility parameters:


The "memdelay" parameter is only applicable for correct applet functions
on some bugged versions of Netscape 3, that don't correctly deallocate 
the allocated memory. This results in filling all the memory after  the
applet runs for about a minute. This can also cause a system crash in
some cases. Later versions of browsers have fixed this problem, but if you 
want to run the applets on old bugged browsers too, set "memdelay" to 
low values, like "10" or "16".
However, this will greatly slow the applet speed, so you have to choose
between speed (memdelay set to 1000 or higher) or slow compatibility with
old browsers (memdelay set to 20 or lower).

The "priority" parameter is mainly for when you run more than one applet in
the same page, and one slows down or hangs.
If an applet runs too slow or hangs because another one steals all the CPU
power, try increasing the priority.
Otherwise, if the applet runs well and others slow down, decrease the
priority. Consider the min priority is 1, normal priority is 5, and the
max priority is 10. Usually a priority of 3 gives acceptable performance
for single applets.

The "fixnetscape" parameter is useful  when the applet is displayed with
Netscape 3, using Win95. In fact, Netscape has a bug displaying
IndexColorModel, and results in fewer colors than normal and unwanted
dithering.
By setting "fixnetscape" to "YES", the effect will run slower on all browsers,
but will have correct colors on Netscape 3.0. By setting it to "NO", the
effect will run faster on all browsers, except Netscape 3.0 which will
display very poorly.
Netscape 4 and Explorer do not have this problem.

Applet animation may appear to run too fast on new faster computers, or when
the applet size is small. If this occurs, the "MinSYNC" parameter must be set
to a value between 8 and 16. The optimal value seems to be 10, but you can
disable this feature by placing a value of 0 if you see flickerings or
excessive slow down.
If the applets steal 100% of CPU power or slows down the browser and Operating
System, try increasing MinSYNC until the system appears to run normally.
Values between 40 and 400 generally fix all the problems, even if the applet
slows down for compatibility.
