terminal output

The game crashes when I change any of the available settings (screen
resolution, graphical driver, full-screen/windowed mode) on the Options ->
Device screen.
The game displays the following error message before crashing:
"A DDraw object has a non-zero reference 
count (meaning it was not properly cleaned up).
COLOBOT will now exit."

Steps to reproduce the problem:
1. Install, then start the demo with colobot.exe
2. Create a new player and go to <Options> in the main menu
3. Select the <Device> page and remove the checkmark from the 'Full screen'
checkbox. Click on <Apply changes>...the game crashes at this point. Changing
anything on this page results in the same crash.

According to my testing, the problem appeared in Wine 1.4-rc1 and is still
present in wine-1.5.13-144-ge3a2e3a.
The result of the regression test:
