I can just hit ok and things seem to run as normal. Anyone know what this is about?

Running XP SP3
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)


I noticed you closed the bug report but I don't understand the issue. Please explain what I need to do on my end to remove the error.

find ext directory under JRE directory and remove xerces*.*

Do you get that when clicking "OK" in the file properties dialog? If so, it is a known bug, fixed in 0.85alpha.
