SUSE :: Weird Permission Change - Impossible?

I have openSuSE 11.2, and just recently I've installed Apache 2.2 on it. I installed php, rewrite and ftp modules - all was OK. I made two accounts which are able to login on the FTP, and should have full access - I made the htdocs (the folder accessible from FTP) have permissions - root and root group should have both read, write and delete permissions. However, when I right clicked the folder >properties > permissions - it said "Folders: Read and write" (or something like that), but "Files: ---"... Always when I wanted to change that, in GUI or terminal - it did the same, it either changed back to --- immediately, or it stayed like that... until I closed the window. When I reopened it, it was the SAME...

I double-checked - Apache was stopped at the moment. I tried to change the permissions of the enclosing folder - still did the same. I do not really understand the Linux filesystem structure yet, but from what I read on internet, I saw that most used install prefix is /usr/local/apache - I installed it there as well. So, I though I shall put the htdocs folder somewhere else - I made a new folder in /var/ called server. But the properties of that folder did the same thing! I.e. it changed back just when I changed it to something else. How can I REALLY change these permissions so they won't change back in a second?
