I have lost functionality in the Operator Properties Panel at the bottom tool shelf.

When I click on a selector or something in the bottom part of the tool self that you can hide and unhide, nothing happens. I can see the options but when I click it doesn't work.

This is what hapens when I use Add > Cylinder.

    $\begingroup$ A better title might attract someone who knows the answer to this. Perhaps something like "Operator properties greyed out" or "Bottom of toolbar inactive" - assuming I'm understanding the question right myself. It's not an uncommon problem. $\endgroup$

If we want this site to be a resounding success we are going to need to be a bit more flexible and patient with beginners. After all, we are here learn and BECOME experts. $\endgroup$

It's likely caused by one (or more) of the many add-ons you have enabled. Try launching Blender from a console/command-prompt and see if any errors are being reported. Failing that you can go File>Load Factory Setting and start enabling stuff while checking for breakage.

Make sure Global Undo is enabled.

For 2.8x and 2.9.

Edit > User preferences > System > Memory & Limits: Global Undo

enter image description here

For 2.7x use CtrlAltU > User preferences > Editing > Undo:

enter image description here

That panel is called the redo panel, because when you change a setting on it, blender actually redoes the previous operator with the new settings.
If blender can't undo the previous operator first, running it again will add it's effect on top of the result of the previous operator (which is not the desired effect at all).

So this panel is disabled when undo is not available.

Ok, this happened to me again and I have figured out what the problem is/was.

If you are rendering with Luxrender and have sent a render off to Lux, while it is rendering it will not allow access to the operator panel. I guess I'm a bit thick not to have figured this out before but there it is.

As soon as you stop the render in Blender you have access back again. This won't stopp the render in the Lux gui if you are using that though, so you can still continue the render and work in Blender at the same time.

Hope that helps

This happened to me for whatever reason, enabling Global Undo in the User Preferences > Editing panel made it all good again.
