Actually, Gwyon the Bard finally nailed the problem on the head on the EZBoard forum. I'll quote him, here, for easy referance:
I had the same problem with the pet window a way ago and sorted it by going into the window setups in the UI setup file and manually increasing the PetInfoWindow height number until the problem was corrected.
So... As it turns out the problem is in the INI file that comes with KeizUI. Seeing as I never use the Pet window, it still had the old default values from waaaaaaaaaaaaay back. Since then, VI has changed the Pet window and apparently the game takes the size value from the INI file, so it comes up too small. I will fix this in the next version of KeizUI!

Also, because I get a lot of PMs with this question...
I finally got the con color to show up in the Target window while still having it flash with Autoattack! Before, I could get it to only do one or the other (and with KeizUI7a, I opted for the Autoattack flash).
So you can all look forward to that feature in KeizUI8. :) I plan to release that the next time EQ has a major patch, but might release it early if there's enough demand for the con color in the Target window.
