why does my art keep disappearing?

after i either click a tool or click on the canvas. how do i stop that?

It sounds like a Blend Method setup issue,
To check it: go to layer panel, highlight the layer you created, and then go to params panel, find the “Blend Method” parameter, double click its value, there will a dropdown list appears, select “Composite” option.

If you would like to know more about these opetions, pls take a look at the wiki page: wiki.synfig.org/wiki/Blend_Method

Also, you can check the default setting of layer Blend Method, which stay in the toolbox, pls change to “By Layer Default” mode.

that was true, but it’s still doing the same thing. what could the other reason be?

EDIT: the other reason was that i was using BLine and not having it sealed off. i was drawing stick figure legs and trying to make it walk for practice
