autocad does not recognize some commands

[Martina Webber]

Good morning, I'm working with autocad 2009 and there are some commands that tell me that you don't recognize them and crush f1 for information.
commands do not work in any way, or if I click on the icon, or if I type the command, or select it from the curtain menu.
the commands that do not work are:
- display orders
- extension
- size
- Witches.

someone can help me, I looked in other discussions, but I didn't solve anything.

What do I do? an update?

 

[Fulvio Romano]

if you give the command preceded by "_"?

But "strike" is not what you give from command line, is it?
Why don't you place the real commands that go wrong, and not their gergal interpretation?

 

[Martina Webber]

Nothing, every now and then it doesn't work anymore. . .

Excuse me, the command is "dead"

 

[PlannerRoad]

but did you install the upgrade 3 suggested by tir?

 

[Tristan]

Are we talking about autocad, autocad lt or a vertical? Italian or German? is the operating system in Italian or in German?

tristan: I'm talking about autocad 2009 in German language
planerroad: I didn't update, but it always worked, but sometimes it doesn't work, I don't know why
