Image insert is not working in IE 6

Image insert is not working in IE 6 (XP SP2). Upload is OK but File browser doesnt send image data back to Image properties dialog.
I get this error: line 359, char 3, error: class doesnt support Automation, code: 0, url: fck_image.html
In Firefox is everything ok.

I have problems with uploading files to created folders with file browser also. (PHP)
