Uploadify IO error #2038 random on Google Chrome

I've installed Uploadify to upload files on my server but it appears that with Google Chrome, there are random IO errors, even with small files.

On Firefox it works great.

Anyone has a开发者_高级运维n idea of what it could be ?

Thank you in advance.

This problem is linked with the last flash 10.2 version on Mac OS X
