I have just upgraded to the latest photoshop and I'm having problems with using the bracket keys for brush sizes. If i go to my brush palette and use the sliders the brackets will work for one use only.Does anyone know how to solve this problem?
Could you answer Chris' questions. And also, are you using any sort of tablet or keyboard emulator or keyboard- or screen-capture application? If so, could you try disabling that and seeing if the shortcut keys then work?
