OK, so my Photoshop has a problem. I go to Filter, and more than half of the effects are blocked off. Can anyone tell me what's happened? >.> Here's a screenshot, thanks.
this happened to me before, I don't remember what I did to fix it but here is what I can think of... make sure it is set for RGB color go to the edit menu to set the color style. if all else fails uninstall and reinstall PS.
Make sure when you make a new document its in RGB. You can change a existing document to RGB by doing Image>Mode>RGB.
my photoshop nvr does this, though if i have a bunch of programs runnning at once then it might quit (ie, firefox, photoshop, limewire, itunes, emullaters)
