Turning off Active X will BREAK text messages, all email.
I asked in this thread a while ago for some help with my text messages only showing headers. This error did the same for email's but I don't use that as often. I didn't get any reply's and the problem was driving me nuts. It would work after I cleared the memory but after a time texts and emails wouldn't work. I then posted a thread and the people were very helpful but I still couldn't get the problem fixed.
I thought Kavana's ROM had some big error with it but no one else was complaining. I downloaded Ricky's rom but same problem. So this weeked I fooled around with my phone believing it was some program I was installing. Even though I only install Google Maps, TCPMP, YGo, and Windows Live. I would install something then restart. I tried installing them one by one then it seemed to work but still after a time was becoming broken. I thought it had something to do with synching corrupted contact data. So I didn't synch but after a while it still came back.
This morning I finally realized that if you turn off active x it breaks the email and text which I assume both use IE active x The bad setting is.....
Main Settings Menu->IE Settings->Advanced Options -> NEVER TURN OFF ACTIVE X CONTROLS.
I think if Kavana, my personal hero, rolls another ROM you should take out this option.
