Me too - just updated to Froyo however
I have an unbranded unrooted legend - updated to Froyo and then conducted a factory reset after formatting SD card - I wanted to start Clean.
I have the same issue, after powerup and then a click near the notification bar renders my phone useless as any further click pulls down the notif bar.
clicking on that part of the screen when in an app causes the app to go funny.
Powering off and avoiding clicking at the top of the screen it the only way to use my phone - - -
This is driving me nuts
Have logged a call with HTC
Is there a way to replace the notification bar?
factory resets or Stopping sense UI makes no difference
