Not sure if anyone else is having the same issue with CAD 2014 but here goes.
When using any kind of Modify command (and in particular the Move command) on blocks, the cursor jumps as if i have Snap mode on, although it isnt. I have both CAD 2011 & 2014 and i have drawn a direct comparison with settings to see what differences there are but nothing jumps out. Interestingly, the more elements in the selection set, the worse the issue is.
We're having to go back and use 2011 because of this one issue and it's very frustrating. Can anyone help?
