I have installed it and put in --enable-user-scripts and I also have --enable-extentions aswell and when I open greasemonkey it opens then it automaticly closes again

Can you explain what you installed?
Because Greasemonkey is kind of build-in in Chrome.
So I do not understand what you installed?
A script?
An extension?

Glad to help but not very clear

I have installed about 5 scripts and 2 extentions

So ???
What is your problem then?

Well I open greasemonkey and then it automaticly closes again....it doesnt stay open

Why do you need to open Greasemonkey its not needed for extensions and user scripts to function ....

Aaah, everything is very clear to me now.
I am really sorry not to be able to help out.
The real question to me is why you even bothered to post your question in the first place.

You must remember it's winter in the Antipodes ...

Perhaps they're hibernating ;-)

Like previously pointed out you do not need to use anything additional (ie. Greasemonkey) in Chrome to enable the use of user scripts and extensions. Keep in mind that a lot of scrips and extensions might not work properly unless you are on the latest Dev build. Read here for more information: http://dev.chromium.org/getting-involved/dev-channel

It seems like you already understand how to edit the target shortcut:

"C:\Path\to\chrome.exe" --enable-extensions --enable-user-scripts

I've moved this into the Chrome Plugin Troubleshooting forum and if you further issues please report back so we can help you.

So I don't need to open greasemonkey for userscripts to work

Because I read that you have to use greasemonkey as the shortcut for chrome to use userscripts
