In CS3 my brushes fail occasionally

Question

I use Adobe CS3 on my iMac running leopard 10.5 . Quite often when I open a CR2 Raw file into the editor I have an issue which is frustrating me. I attempt to use one of the brush tools such as the blur, paint, heal, clone etc. and when I depress the mouse button to begin dragging over the area I want to modify the brush only applies the effect to the area where the brush first touches. I can still move the brush cursor to the areas I want to modify but it has no effect there at all. I have found if I save the image as a tif or jpg and then restart Adobe and reopen the file, then the brushes work properly. Is this a known issue to some of you ?

Answer 1

I only ever have one image open at a time . It does not happen with every image I open either. It seems to be a sporadic kind of thing at this point. Keep in mind that the image has just been opened from ACR into the Editor and has not yet been saved as a .tif or .jpg or anything else at that point. So when the problem occurs I have to save the image as something, usually I save it as a .tif and then I restart Adobe CS3. I seem to recall that I tried just saving the image and beginning to work on it and it did not work until I restarted Adobe. Next time this occurs I will verify this .
       I do not know what you mean about the brush having no shape or dynamic. If it is the clone tool I am having the issue with I simply choose a brush size.
