when selecting and object or face, I also select objects or faces behind that object or face. for example/ if I have 2 disks one above the other and I go into top view and select the top disk, I also end up selecting the one below. it doesn't always happen, but it makes some tasks nearly impossible to complete, like making UVs.
Another issue I have is making UVs. even though all the faces on selected at the same time, some end up flipped. and no matter how I flip them, horizontal or vertical, they're still red.
