MMB not working when scaling in vertex mode

I’ve asked on chat and searched the knowledge base, and can’t find an answer to this. I’ve been folowing along in the Blender 2.0 official guide and am in the mesh modeling chaper. I need to scale a selection of verticies and constrain the scaling to one axis. I start the scale by pressing S, then moving my mouse vertically and clicking the middle mouse button. No matter what combination of these I try, the scaling is always in the X Y and Z directions, and nver constrained to just one.

When I’m in object mode, constraining scaling this way works no problem. I can also rotate the view with my middle mouse button. What’s going on? Is this a bug in blender? I’m running V 2.5 on Windows2000.

You need to press the MMB first and then move the mouse in the direction you want to scale.

In new Tuhopuu II version, (see post in Blender Chat forum by ztonzy for latest release), all you need to do is press X, Y or Z for the axis you want to scale along.


You can also push the alt key to emulate the middle mouse button. So if you wanted to scale in one direction you would hit S, move the mouse in the general direction of desired scaling, hit alt+LMB, then scale to right size. This is useful if you don’t have a mmb. Later

Looks like it was a blender bug after all. I downloaded 2.28, and everything is working fine now.
