I haven't been able to run lime pro either since 4.10 I did a full restore two days before I upgraded to 4.10. I run a
HP 3100+
512MB PC2700
160 G
NVIDIA G-FORCE 128MB VID CARD
AMD ATHALON BOARD
W/ SONY DVD RW

I do some media not much.

I load LW and start running 10-20 minutes and my system is freezing up. I even have ahard time shutting down. It is like the active ram is overloaded but I show like 90% idle process in windows taskbar processes.
