Actually, the way to get these things addressed with any public-sector agency is during the RFP stage. The consultant they selected developed a solution like this is because the RFP didn't specifically call upon them to do something different.
The fix - and it's not an immediate fix, but it *is* the one most likely to prevail over the long haul - is to educate KCATA management about the potential market they're impacting and encourage them, during their next system upgrade, to take users of other browsers and systems into account.
If you push for an immediate fix, they haven't budgeted for it and it's too easy for them to say no.
