ADAudit Plus MySQLD-NT 100% CPU Utilization when running reports

ADAudit Plus MySQLD-NT 100% CPU Utilization when running reports

Our office is currently running the latest release of ADAudit Plus 4.1.0 (4141) and have issues with our server becoming nearly unresponsive when loading particular 'User Logon Reports' due to the MYSQLD-NT process pegging the CPU at 100%.
 
We can reproduce the problem every time when loading the 'Users logged into multiple computer" report.
 
Is this a known bug?  If so, is there a patch/update to correct this?
 
Thanks
 
Chris
