Here's a heads up for Birmingham schools running HR Portal -
I've tested it on Win 7 SP1 x86, Internet Explorer 10.0.5, Adobe Reader 11.02 and Policy Central 18.104.22.168 and it works!!! but you need to enable Compatibility Mode in IE.
Enable the Menu bar > Tools > Compatibility View settings. Tick to enable 'Display all websites in Compatibility view' then click Close.
Optionally remove the Menu bar and HR Portal will now run correctly.
