disable folder size enumeration

I have the new Prof verions and The old 1.8 free version had a settting to disable folder size enumeration which slows down the page updates.
Can you please tell me the configuration field to insert to disable this feature?

thanks

Hi Alex,
Pro version didn't have a constant for disabling folder size calculation but I have added it as you requested.
The option will not appear on the preferences page though, you should edit calculateTotalSize constant in inc_config.asp.
I am sending the update via email.

you rock man
thanks
