Can't disable uniform scaling

[namelessone]

When you scale anything, by default it was non-uniform for me (no fixed ratio) and I could go uniform by holding Shift. Now it's reversed for odd reason (haven't used sketchup for months) - by default its uniform, Shift enables non-uniform. Can't figure out how to fix it. It's frustrating to hold Shift for pretty much all scaling.

This is only true if you pick a corner of the bounding box. It defaults to uniform.
Picking any other handle scales against its opposite point, unless you hold shift.
