Memory usage is set to high, which I presume is the default. For the record I am
using an IBM Thinkpad T42 with an ATI Mobility Radeon 7500. Interestingly I was
speaking to Matt Hamann yesterday and he was having issues with LDView too, and
he has an IBM Thinkpad T30 with the same graphics chipset so it looks like there
is possibly a problem with the way the driver is written.
