pen tool suddenly seems broken and this only happens when making a mask path;
at the first click a vertex is created, at the second click a new vertex with created on the very same vertex that is made from the first click no matter where i click on. At the third click, another vertex is created on the very same point where the first and the second vertex is created and now the path is visible and it appears to be closed at the same time. But it is detected to be a non-closed path when i try and move the vertex with a selection tool. Vertexes are created on random points after the third click and the path also forms a random shape.
It seems that the pen tool switches to the add vertex tool after the first click automatically.
I tried with restarting a computer and even reinstalling and updating the program but it's still not fixed.This problem is only shown on the very project that has the trouble with. i have imported the composition to the new project and the problem is still shown while another composition i made in the new project seems ok.
FAQ, How to, Performance, User interface or workspaces
What happens if you use the pen tool to create four points forming a square and then you click the first point again to close the path? Are you using the Alt/Option and Ctrl/Cmnd keys to modify the pen tool to help you adjust the path? When you try and edit existing points to you select the path in the timeline and then change to the selection tool? I'm not seeing any bug or change in behavior and I have not seen any bugs reported.
If you are not holding down the shift key and your mouse/tablet/trackpad is up to date and seems to work fine in other apps I don't know what is going on. This is not a normal bug. Try updating any drivers you have for your pointing device. Try creating a mask on a comp sized solid. Try creating a shape layer with the pen tool.
Oh, and make sure your version of AE is up to date using the Creative Cloud app.
