Permanently turning off Palettes

Hi everyone. I'm halfway though a trial of Draftsight Premium, looking to see if it's a viable alternative to AutoCAD LT.

One question I have; how can I permanently turn off the 'G-Code Generator', 'Home by Me' and '3D CC' palettes that appear at start-up? I'll close them but as soon as I restart the program they're back again!

Hoping for a permanent switch off!

Thanks in advance.
