[power-pro] *Timer Autosave in 4.7 does not work

[ratanasiha]

I want to use PowerPro on a USB Memory Stick and want to reduce the 
writes on it as far as possible. But whatever I set in *Timer Autosave 
PowerPro updates the pproconf.pcf every 5 minutes. This was checked in 
WinXP with PowerPro version 4.7. What works is *Timer Autosave Now. But 
no value like 0 or 1800 or anything else.
