Control handles don't control curves (sometimes)
Steps to reproduce:
- Open Inkscape.
- Draw a shape with the pen tool containing several nodes using "Create regular Bezier path" mode.
- Switch to "Edit Paths by Nodes" tool and select "Show Bezier handles of selected Nodes."
- Left-click on a node to reveal control handles. You may need to [Shift > left-click-and-hold > drag] handles out from node, if they don't readily appear.
- Left-click-and-hold a control handle, then drag it around. (Out of confusion more than anything else, I also tried pushing the Shift, CTRL and ALT keys [in separate instances; not at the same time] before left-clicking on handles -- both pushing the key and letting go after left-clicking and also holding down the key while clicking and dragging -- but realize that these may not be acceptable/expected ways to control a control handle.)
What happened?
The control handle spun around in different directions and its length changed, but this had no bearing on the shape. The handle just moved around the node, pointlessly. If this behavior took place with the control handles on one node, it took place with all of the control handles on all of the nodes in all of the shapes in the document.
This occurred once, after installing and opening Inkscape for the first time, very recently. Because I haven't been using the software for very long, I don't know if the issue is retained within a document after saving, closing and reopening the file or if control handles that were working before could suddenly stop working. But, I have witnessed correct, expected control handle behavior in other new documents, since this occurred.
I'm concerned that this is an indicator of general software instability, which is why I'm reporting it. I apologize if I've reported this problem too quickly before exploring it further, myself. There seems to be some urgency to this issue because the software is useless without editable control handles.
What should have happened?
When I drag a control handle around (using the tool specified in the steps, above), the curve(s) controlled by the node should change according to the positioning of the control handle.
