My zbrush4 R3 is with this strange behavior. Since I installed it the common brakets hotkeys (equal to photoshop) are not working. So my intuos 4 does not do anything when I use the wheel, it is really annoying. Im using “S” hotkey to adjust size but it is a pain in the ash… I have searched the web and forum and i found lots of things, even pixologic own support pointing to Zplugin>Misc Utilities> and there I was supposed to find Brush increment, but it is not there, does not exist… there is only “InteractiveLight” and “TextFileViewr” so I cant redefine the brackets as a hotkey.
I have not used an upgrade file to z4r3, instead I got the full instalation, maybe there is a difference, i dunno, just guessing here… anyone there with z4r3 could take a look if the brush increment is inside Zplugin>Misc Utilities> ?
