Slow Response inputting values

Hey lot,

A quick overview of my problem here (didn’t really know where else to post):

Every value I want to change, such as the number of segments and heigth of added objects, coordinates, etc., either mannually or with the arrows given, display only after a looong while or even not at all.

I have
OS: Windows XP
Python: 3.0
Blender: 2.49b
System: Core2Duo 1.8GHz , 3GB DDR2 RAM
Medium: Laptop

I still have the default configuration of blender.

If anyone can help me on this one I’d be gratefull.
It’s rather irritating not too see the exact value I type, or if I’m even typing a value. at all

Many thanks in advance,
