None Fractional Dynamic Charge in 4.6.1?

I was told that this error was present in geant 4.5.2 so I've upgraded all my source code to GEANT 4.6.1 and things seem to be working OK.I appear to be producing the heavy ions like I expect. However I am still having problems with fractional dynamic charge. I've gone to the web-page

http://cmsdoc.cern.ch/~hpw/GHAD/LCGPage/auto_subentry8.html

And installed the following lists QGSP 2.8/QGSP_BERT 1.2 /QGSP_BIC 1.2 with the newest Packaging library 2.5.

I tried running my program 3 times using each of the above physics lists, yet when I look at the dynamic charge of my ions I still get fractional charge values. It would appear that anything heavier than an alpha carries this fractional charge. Has anyone had this problem in 4.5.2 and had it solved in 4.6?

Cheers

Jeff
