Capitalism 2 and Capitalism Lab Forum

Full screen works perfectly fine.
But when I change to windowed mode, no matter at the start or change in game, black screen is shown.
The game is still running, when i click on the screen, the sound will change. No error window pop out.
Can someone help me to solve the problem?
I have tried to delete the CONFIG.DAT file and reinstall the game.

You may try the following solutions:

SOLUTION 1:
1) Right-click on the Capitalism Lab icon to open the properties window.
2) Select the “Compatibilities” tab and check the Windows XP Compatibility option.
3) Enable the option "Disable display scaling on high DPI settings."
4) Enable the option "Run this program as an administrator."
5) Run the game.

SOLUTION 2:
On the Capitalism Lab launcher, you will see the option “Force running in 1024x768 full screen mode.” (below the [Login] button). Please select that option before clicking on the [Login] button and see if it will run the game successfully.

I have tried both solutions.

Solution 1 doesn't work. The windowed mode still gives me a black screen.

Solution 2 did help me to start the game with full screen, but when I change to windowed mode, black screen comes back. So I still can't play the game in windowed mode but only in full screen mode.
