I have new problems.
1)-  I begun using Librecad and making a drawing for practicing, starting from an existent .dxf drawing.
Many commands work but I can not delete entities.
i select some entities, I click the DELET pushbutton in the toolbar, the icon enlights but nothing happens in the drawing. in the bottom of the screen, near the mouse picture, "select to delete" appears; I click the SELECTION POINTER pushbutton: the selected entities deselect.

This happens most times. Once in many many  times the DELETE works correctly.

2)-  Clicking WIDGETS -->TOOL BAR CREATOR after 2 seconds Librecad switches off.

Which can be the possible reasons?

Thanks in advance.
