Hello
Help please
when i first downloaded inkscape, i was able to draw a line with the bezier tool

and then curve the line using the Edit path by nodes tool

in the center of the line by clicking and dragging up. But now when i try to draw a curved line nothing happens, the line does not move and i am unable to curve any line in any way at all. I do not understand why i am unable to curve any lines at all, no matter what i try the line will not curve and stays flat. I have watched all the videos on youtube and searched for hours on google for a solution but nothing and i really want to make a curved line so that i can curve some text like i did on my first project with inkscape.
Any help would be great
Thank you
