i uninstalled the latest update for this reason: moving objects in increments using shift/arrow seems to be broken. i use this a lot, like when you drop a terrain & it buries itself wrong, or you work on the terrain some more & it ends up similarily repositioned, so then you have to put it back. the shift arrow thing no longer works & hand-dragging the terrain or ground is a nuisance. what the shift arrow thing does now is just flip thru the object menu. 

i tried cancelling the update. this did not work, it claimed something got corrupted, the version name was still there & the problem as well. ended up reinstalling during the wee hours.
