Tab placement on customization

Hi,

Is there any way to control the tab placement on a customization? We implemented one on our MES screen and for some reason when you click on the tab for the first time, it it drags it down below the rest of the tabs so it ends up being it's own window. You can drag it back up, but it's annoying and for the shop people that don't use epicor except for clocking time, it's confusing. We haven't been able to see anything that controls the tabs. If anyone could point us to a good help file or training course that explains how to control the tabs that would be great. I would also like to be able to create layers of tabs in a dashboard like they have in the main program but have been unable to figure out how to do that.

Thanks,
Brandon
