Web Front end locks up NVX Pioneer ed

[5bellies]

Has anyone else enocuntered this?
I am running an NVX Pioneer Edition approx 3 years old

Model: ReadyNAS NVX Pioneer Edition [X-RAID2]
Serial: ------------
Firmware: RAIDiator 4.2.21
Memory: 1024 MB [5-5-5-24 DDR2]

If I log on to the front end it is a little sluggish, but If I go to Addons and then to installed it hangs for an eternity.
If I do the same using Firefox I get the following error

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

For info
The PC I am using is a Win 7 Ultimate 64Bit with 16Gb RAM all patched with Forefront AV.

Everything else seems to work OK - done the obvious (reboot / Factory)

Thanks in advance
