Can't see folders or create subfolder in image browser in IE

I have CKFinder 1.4.1.1 and I have problem only in IE. In FF 3.5 is ok.

When I upload files I see folders on the left side normaly and I can create subfolders.

But if I want to add image I don't see folders on the left and i can't create subfolders. I only see "Images" without [+] icon infront and dropdown menu is grey colored.

I have "userfiles" folder with chmode 0777 and folders "files", "images" and "flash" inside with chmode 0755.

What is the problem?
