Webix not working in IE9. Why?

I keep getting an error on the webix demo pages saying “webix is not defined.” I am using IE9. I tried it again on my smartphone, and it worked. I don’t understand why it doesn’t work on my computer though. I can’t get most of the live webix samples except for the ones that appear alone in the page.

I really like the idea of webix, and I really want to use it, but if it doesn’t work on my computer, that won’t do. I guess I should also mention that this is a work computer that may have security restrictions. I have used other js libraries with no problem before. I don’t know why webix has one.

The samples in package was tested and must work with IE8 and IE9
Are you loading the problematic page by http ? Due to security restrictions ajax operations will not work if you are loading page directly from file system.

Do you have some error messages in dev. console ( press F12 to check it ) ?

My boss has google chrome for debugging. Curious, I tried it in chrome, and it worked. Then I thought it must be a browser problem.

So I upgraded to IE11 from IE9, and that fixed all my problems. I think we’re going to have to upgrade all the computers in the office. I looked at the debugger, and there were a whole bunch of “not defined” type errors. Since the only thing I did was upgrade IE, I’m pretty sure that was the problem.

I don’t like using IE, but at a big company, that kind of stuff is considered business class, and more professional, so I don’t have a choice. No one (including me) can get other browsers installed. Something to check up on?

Is the problem occurs with some standard Webix demo ? I have double checked all common pages in IE9 - all seems to be fine.

The problem is with some of the webix demos such as:

http://webix.com/demo/tree/basic/
http://webix.com/quick-start/datatable.html#!/1

There was a little red tag in the upper right hand corner that said “webix is not defined.”

Also, I wrote up some webix code, and ran it in IE9, and that didn’t work either. I ran the same code in chrome, and it worked, so I knew it had to be a browser issue. Being that this is a work computer, there may have been some kind of security, but the fact that the upgrade to IE11 fixed the problem is puzzling to me.
