Hello everybody.

I just started using this software program and I have a problem. I am sure it must be something very silly but I have not been able to figure out what's wrong. When I try to draw a figure I can only see this and not the figure on the screen as usual. I attached the screenshot of what I see.

Can anyone tell me what I must change to draw the figures as usual?

Thanks a lot in advance

it looks like u dragged out a circle? Have you checked the opacity levels in the fill and stroke panel?

That was it. Thank you! I knew it must have been something very silly
