BatteryBar causes windows explorer stop working

[pgpayton]

After installin BatteryBar 3.54, when I start my laptop there maybe a chance to wait windows explorer to response, after that got the message said windows explorer stop working then I have to restart the windows explorer. I uninstall the BatteryBar then the issue is gone.
My Computer environment is
Windows 7 x86
T4200 CPU
3GB RAM
plugin power using windows Balance power scheme

Thanks for your help
