I've recently installed version 1.2.2 of Inkscape.  

So far, I have not been able to get the Bezier tool to work like the tutorials say it should. 

Every time I end the line segment, by either double clicking or hitting the enter key, It closes the shape rather that leaving it a Bezier path. 

I have "None" selected as the shape type, and "Create regular Bezier path" selected. 

Thanks in advance for any feedback. 

Before proceeding further, I'd reset the preferences. https://inkscape.org/forums/questions/getting-back-to-square-one-and-starting-over-its-easy/

Thanks Tyler,

I clicked the "Reset Preferences" button, and restarted Inkscape. 

When I re-launched Inkscape, and tried the Bezier Tool again, I get the exact same result. . . It always closes the shape. 

Can you check the toolbar when the Bézier-tool is selected - especially where says; Shape?

NB that open paths can have fill... that can look like a closed path.

I have "None" selected as the shape type, and "Create regular Bezier path" selected. 

Three points always ends up looking like a triangle. 

Easiest way for us to check is: save an example file and upload here. And for you: check Status Bar about your stroke and Fill and Stroke panel for Stroke width.

Polygon, 

Thank you for the help.  Before submitting a file for you, I checked the stroke and fill settings.  I found the Fill setting was the issue. . I set it to no fill, and the Stroke to 0.1mm. . . All is showing up as expected. 

Thank you all for your patience while I'm just getting started with this program.
