The pencil tool is appearing as a thin blue line no matter what size it it

I am new to flash and animating and everything is confusing and going wrong! First of all when I choose a colour for the stage it stays white. Also when I draw with the pencil the strokes are these blue lines even though I chose black. And if I adjust the width of the stroke it stays the same tiny width. This is so frustrating ugh why can't humans just interact with each other nowadays and have real lessons available instead of me trying to teach myself Please help me. I would really really appreciate it. Thank you.
