I was very excited to see the new memory configuration.
I had previoulsy tried the "Mathias Tweak" with miserable results. I thought probably because i'm not computer savvy enough and I just didn't know what I was doing.
But having tried the new facility on all three settings recommended for 1GB+ machines it all went horribly wrong. each time I rebooted with the new settings the display settings were all over the place - poor colours huge icons - and either I was immediately frozen or nothing would respond and if I tried to open any application a message would say no memory. Each time I had to reboot in safe mode and restore my settings.
So the new memory manager is no good for me and I'm stuck with being able to only access about 650mb = 42% of my available memory.
Clearly i am not computer savvy enough but has anyone any ideas?
