How to turn off calculating dynamics

[Pitcher]

I have several fires going in a picture. I want to make some minor changes in another part of the picture, but every time I make any move, the computer goes into calculating dynamics. It is taking almost forever to get the changes made. Is there any way to turn off the calculating dynamics until I am ready to render? Thanks.

I believe SHIFT+8 will toggle hair and particles ON and OFF.

 

Also, in Tools>Options>Global there is a check for "Particles/Hair always off".

 

 

In either case, you need to remember to turn them ON when you go to render or they will not show.

 

 

 

In View>Toolbars you can enable the Draw Menu that has a button for toggling hair and particles ON and OFF.
