A lot of things could be done about this, and the truth is, it would take just minutes to fix annoying messages like this one.
Easy and quite good solution would be to change it to Display_Message with some fancy font colour. Poll interface could be also changed, plenty of things can be improve here.
But I'm affraid there are many more important things to do by devs, like nerfing archers, nerfing ranged, nerfing, nerfing and more nerfing, so we will probably never see interface fixed.
BTW: I would have done this by myself long time ago, but crpg source code isn't released to public unfortunatelly
