GUI and Yatco chat modifications

Mannimar

I've started building my own GUI, and one of the first things I'm trying to do is shape up my chat script to fit my needs, and I'm kind of stuck on styling the chat's tabs. I want to have rounded corners, but I don't feel like I understand the script well enough yet to figure out where to handle that modification

So, I've managed to fix up Yatco as a GMCP chat script with rounded tabs with a gradient. However, Any time I resize my window, move into my scripts or do anything not on the primary window of Mudlet, the tabbed chat jumps to a new part of my screen, forcing me to have to correct it, every single time I go to code something.

Does anyone know why it's doing that or how to fix it?
