I notice alot of posts detailing that their Home Screen Button vibrates, but does not work. I had the same problem. I don't know if this is correct but, I think if you use the same Launcer in a froyo ROM, then switch to a GB, it does not always work right. I used Tag Home in my previous Froyo ROM, then went to UD's GB. My Home button did not work. Thinking it was the ROM, I then switched tp PE 5.0. Same thing. Out of frustration, when it asked which home I wanted to use, I pressed LauncerPro. Bingo....it worked like a charm. So my recommendation, if you have the same problem, try a differnt home. In my case, I am glad it happened because now I found this ROM and absolutley love it!
