I dont seem to be having this problem likes? I havent looked at your code but how far differnet is it from Perdi bottom target windows?
I know there is a problem with the con color getting borked when you camp to char select and log an alt in likes.... I have never been able to find what the problem is with that

Its the tier indicator that sets the con color and i played with putting multiple copys of that on differnet pages and on the parent etc but it dont make no differance.... so I just put it down to duff SoE DD getting sent when you log from a high lvl toon to a lower one.....
