this bug was fixed successfully awhile ago with an OS upgrade.
Hold ALT and type "EACE" to check your version (or Options->Status, whatever)
The latest Verizon version is 126.96.36.199. To get the upgrade, go here and follow instructions: BlackBerryÂ® Software Updates
You can get more up-to-date OSes from other CDMA carriers, but IMHO the Verizon one is fine and I've been using it for months without any major bugs.
