Gentlefolk; I have seen other posts on this, just adding my own experience with the default Mail app failing. All was well until one day the email mssgs on my AOL and Gmail accts stopped appearing. All I had was a white screen beneath the Compose icon.. Local Verizon reseller had no info...turned off Premium Texting option, did no good. Called Verizon tech supprt today and they had me pull the battery and SD card. No luck. Finally the second tier tech suggested the app K-9 as an email replacement. He sd looking in the HTC tech logs, this appears to be a known problem and they are working on a fix. So far, K-9 appears to be working.
