Click problem

Hi all,

I using fckeditor and it's great. Today do upgrade, and all work fine. Only one things no. Example: Upload image work fine, edit image size border and etc. But cannot add picture to text. Click to OK nothing do. Same problem is with links, smiles, flash and all with popup. Whats wrong?

I forget say:
OS: linux
scripts language: PHP
browser: firefox


btw I'm sorry on my poor english
