when did they change the build system?

i havent played for a couple of weeks, but when i logged in to do some building today, after downloading the newest patch, ive noticed that the build system has changed!

whenever i try and pull on one side of a prim now, it morphs both sides, not just the one side. obviously this is causing a load of problems already, and ive only been screwing with the upgrade for an hour now... editing things in the middle of a group now makes that object extend into objects they arnt supposed to, sizes are being doubled (since both sides are moving at the same rate) and its causes countless other little headaches already, and i havent even tried to build anything nearly as complex as i useto yet.
is there any way of changing things back, making the side i grab move alone? or have they finally gone and shmucked up SL permanently this time? i cant see this change being benificial in any way..

There is a check box at the top of the edit window for stretch both sides. It sounds like you checked that accidentally. Just uncheck it.

ahhh wow, figures it woul be something simple that i'd totally miss. lol
thanks for the heads up.
