When press Extrude Button, i can't modify extrude options (i have the same problem with Bridge, Bevel and Add Divisions).
Toolkit problems: Manipulator tool don't appear
Accepted solution
You may have accidentally disabled your history. (That will cause what you are seeing.) At the top of your screen, there is a small icon that looks like a clock. (You may need to click on the vertical bars to expose it.) Make sure it is enabled, then try your extrude again.
