I too have had the same issue with the my verizon app, the problem for me started when I upgraded to the .1015 OS version. Haven't found a fix for it yet I'm afraid.
To turn on compatibility mode, go to Options->Applications, highlight the app then bring up the menu and select 'enable compatibility mode'.
I am having the same issue as well. Started with the OS upgrade as well. Just swapped out my phone under the warranty and the replacement is doing the same thing. Thinking must be an issue with the OS upgrade.
