I will try that again. I know I tried it last night with Rom Manager. I have the first version of Froyo that was released. I never downloaded the 2nd one cause I read of a lot of people having issues with it.Have you applied a market fix?
I know I was having this problem with SetCPU, it would say downloading for days after putting on Froyo, but never download, and never show up in the notification bar. The way I got it to quit FCing finally when I hit "Cancel Download is I opened the Market, clicked the Menu button, then Downloads. When I found the offending app in the list of downloads, I long pressed it, and this came up with a sub menu which allowed me to cancel the download. When I then went to the app info page in the market, it downloaded just fine and installed just fine. Try it.
