TinyMCE folder is missing... FCKEditor content image adding not working...

I've found out, that adding image in content doesn't works anymore. JavaScript error is reported

By adding folder assets/plugins/tinymce/jscripts FCKEditor works!

The problem is in missing file in that folder: assets/plugins/tinymce/jscripts/tiny_mce/tiny_mce_popup.js

Thanks. This problem is solved by 1.0.10RC.
