text message alerts only when screen turned on

[jay1200]

Hey guys. not sure if anyone else is having this problem. randomly when my phone is on but the screen is off, my text messages are not coming through. WHen i turn the screen on by tapping the top button on the phone, all the text messages alert me. these text messages show the time i turned the screen on, not the time i really received them. anyone have an idea how to fix this, or why its occurring. I am using SPb phone suite, HTC Home not sure if its a glitch in either of these programs as well. ANy and all responses are greatly appreciated.
