Hallo,
I am having an issue for months now, I think since cura 4.2 or so, now just updated to cura 4.6.2, hoping this would finally work again, but it doesn't. Since I do not want to switch to another slicer, I am now seeking help here.
My issue is, that the only way I have to select an object is through the Object list on the lower left. clicking anywhere in the 3d view, no matter how clearly I click the object, it will deselect. Hence I cannot drag an object at all. When I want to move an object, I have to select it in the object list and manually type the coordinates. This kind of works. However, rotation is impossible, as there is nowhere I can enter an angle. So I end up starting a 3d program, loading the model, rotating it there and loading it back into cura. Not a very nice work flow. Other options like placing support blockers or so have of course also become unusable.
I am running Arch Linux with kernel 5.7.10, Python 3.8.4 and Cura 4.6.2 (this package https://www.archlinux.org/packages/community/any/cura/ ) on i3 tiling window manager. This issue now persists for months, while before it was always working.
I have no idea what the reason might be :-(
Hoping someone else encountered this and solved it somehow :-)
P.S. Generally it would be nice to be able to enter rotation angles instead of just being able to rotate through dragging.
