I knew I was going to start having problems when the ability to move switches with other switches was introduced. I can't even figure out how to approach this puzzle.

Level 11 is unsolvable as one particular piece will not attach to any of the pegs. There are multiple places it could go... images I have verified integrity of game files; I also uninstalled and reinstalled the game....

...the switches are just not a good thing. Up until they came I always could use logic to get the first tiles placed and then try with the rest but with the switches you can literally screw the whole board up in so many ways, I have absolutely no idea how to even start trying the different ways out (from the 3. or so switch level on, the first ones were kind of manageable). Can anyone help maybe with a tip how to approach these later switch levels?...

Its uncomfortable to select a piece an hold the left mousebutton (and click the right to rotate). One left click select the piece, another left click unselect the piece

title says all, anyone got any clue how to do this? there are simply too many ways to move the switches around. Will this continue in further levels? I consider myself pretty insightful, but there are just too many options imho.
