VZAccess using CPU cycles

[scr]

VZAccess Manager is using 40% to 75% of my CPU cycles if it's connected or simply open. This constantly drives my CPU to 100% and slows all activity down on the computer to the point of being useless for anything but running the access manager.

Once I close the manager my System Idle goes up to 77% to 80% and the computer goes back to normal operation.

Given the fact that my computer is far from the latest and greatest it normally does all I need except when the Access Manager is open.  CPU is 1.8GHz with 1GB of ram running XP sp3.

Is this normal?
