I have been having about 1 ctd/lockup per night. As far as I can tell, nothing wrong with my computer. Only started happening since 1.10 release. Have read & heard many people with same problem since 1.10 came out. Also, vox sometimes just stops working. Haven't heard any acknowledgment from HTC there is a problem, but from past experience I feel comfortable it will be fixed if is a bug. Just a blind leap of faith.
Now what I want to know, how come ctd/lockup never happens when you are in tower or just taking off? Always seems to be after grabbed for 10 minutes, in heat of battle, couple kills in the bag or getting ready to pull the trigger.
