XFCE locks up on me

[David Fletcher]

I've been recycling an HP Pavilion ze5232 that was given to me rather
than dump it.

Never attempted this before but I've completely stripped down the
laptop, fitted WiFi antennas, put it back together then fitted a
Broadcom based mini PCI card. Ended up putting XP back on to use the
BIOS flashing tools, installed Ubuntu 12.04 dual boot, and used the
instructions I found to flash the Broadcom chip with Linux firmware.

Now, the laptop is working with WiFi but it's not got enough horsepower
to run Unity properly. So, I installed xubuntu-desktop.

XFCE works, except I was using Chrome with ebay to purchase a new
battery for said laptop. Got to the stage of checkout where it needs the
PayPal password. I clicked on the top edge of Revelation which was
underneath Chrome to retrieve the password, end the desktop locked up.
The mouse cursor changed from the arrow to a hand, carried on moving
around but everything stopped working.

Only thing I could do was hold the power button in to force the laptop
to power off and try again.

Logged back in to ebay, tried to pay, the damn thing locked up exactly
the same way.

So, I guess I'd like to know if anybody else can reproduce this?
