Your Java version is ancient! Please update your Java to the latest version: http://www.java.com/en/download/ .

• When using a 32-bit browser on a 64-bit operating system the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp .

Your graphics driver is outdated.
Check http://www.amd.com/ for an update, probably this:
http://support.amd.com/us/gpudownload/fire/previous/Pages/fire.aspx?os=Windows%20Vista%20-%2064-Bit%20Edition&rev=8.911.3.4

Problem fixed. Thanks.

Just for the records, what was it ? Java or graphics driver ?

Java.
