Short description of error
During import, the cursor becomes a black square with changing numbers. After importing, the cursor does not change to normal but remains a black square with four zeros. In order for the cursor to return to normal, you need to change it somehow (go to edit-mode or something like that)
Exact steps for others to reproduce the error
1 - open new scene
2 - import .obj file
3 - now you have the wrong cursor
