Hello guys ! I didn't worked with the configurator before and as a newbie for configurator, I haven't managed to use such type of downloaded panels yet. Ever time, when I used to click on an mxp file, the extensions manager launched and then after suddenly got quits with a 'quit unexpectedly' message . I have installed the Leopard 10.5.4 on an intel machine. Photoshop CS4 trial version . Could anyone have any idea about this or something doing wrong ?
