Cannot disable auto-startup on Mac OS X

[vev]

AUTO-STARTUP:
There is a possibility to add Collanos Workplace to auto-startup items on your OS. It can be done in 2 ways:
1) Check the "Automatically start Collanos..." check-box on the login screen.
2) Go to Tools entry in the main menu and navigate to "Preferences... -> Collanos Workplace -> Account Management" and check the "Automatically start Collanos..." check-box.

PROBLEM:
Unfortunately *disabling* this feature still doesn't work on Mac. If you have a problem with Collanos Workplace starting automatically on your Mac and you don't want it to do so, you could try this...

SOLUTION:
The solution is currently a manual workaround:
1. First, make sure to disable the described check-boxes.
2. Go to your Mac "System Preferences -> Accounts -> {Your Account} -> Login Items".
3. There you should be able to find all the applications set to start automatically on OS startup.
4. Disable the unneeded applications.
