I'll ask my co-dev if he can think of anything - no-one else has ever had this problem that I know of.
Could I ask what your system details are? Windows version / CPU / GPU etc, anything that might give us a clue as to what's causing this. Thanks.
Hooray! My brilliant use of this computer and your amazing concern for this game enabled me to put the game in window mode where before it was not. Wow! Now I get to play. Thank you, thank you. Betty
Yay! So glad you got it to work! I'm sure it was 99% down to your brilliant use of the computer! ;-)
