percent loaded at 0 on internet explorer 8

[Faisons Le mur]

Hi,

I've a problem with the BulkProgressEvent in Internet Explorer 8,
percentLoaded is everytime at 0.
In Firefox or Chrome it's working well, but not in IE8.

I've run the testsuite (http://www.emptywhite.com/bulkloader-assets/
test-suite/TestSuite.swf) to know the problem come frome my code
implementation of Bulkloader but the problem it's the same, on IE8,
the "testPercentLoaded" status is "error" (Status: error,Time:
0.389,Failure:,Asserts: 0,Stack:Error #1009,null) and on Chrome the
status is "suscess" (Status: success, Time: 1.517, Failure:, Asserts:
2, Stack:).

How can i resolve it ?

Thanks !
