Okay, to change the default window behavior, you need to edit the style file associated with the style you are using. I changed the bordersize to be 0, then changed the tab style to get rid of them. I don't remember the exact values I used, but I can look them up when I get to my config file again.
It is also possible to set the default window position and size by saving the configuration with the programs in the positions you want. This was useful to make iGuidance show up full screen with no border.
Just remember, when you remove the frames, you might remove the possibility of moving windows.
