I recently upgraded to IE10 and found agfood.ie didn't like it!
Once in the Main Section, switching from say "Herd" to "Movements" by clicking on the tabs doesn't work, have to exit and start again.
Also when registering a calf the options are slightly different and even though I put in a proper Dam number it would not let me continue saying it was not valid, this was despite it being able to correctly locate the breed for the Dam!
So if you're prompted to upprade to IE10, don't for the moment if you use agfood.ie
I see the AIM system will be down for a short time on Wednesday, maybe they are loading an updated release, I'll check it afterwards.
