I've managed to create the launcher with UT2k4 Launcher Factory and even double-click it but...
The game has launched normally, although it just doesn't react to mouse button-clicking.
Yes, I can move the cursor and use the keyboard as usually, but I can't even click the Singleplayer button.I keep clicking but it doesn't react and is continuosly driving me mad.

Is there any way to fix it through console, maybe?
If that will help, my configuration:
iMac G5 {
Mac OS X Leopard 10.5.8
CPU - PowerPC G5, 2 GHz
RAM - 2 GB
Video - ATI Radeon 9600
Mouse - Logitech UltraX Optical }
Thanks for any help.
