All my tools in Photoshop CS5, including the brush, eraser, healing brush, etc. are only making dots, instead of drawing smooth lines. When using the brush tool, for example, if I click down and drag my mouse to draw something, only the initial dot for where I clicked down gets colored in. Does anyone have any ideas as to why?
Could you please post a screenshot with the pertinent Panels (Options Bar, Brush, Brush Presets, …) visible?
Does anything jump out to you that could be causing this problem? Also, my lasso tool doesn't work properly as I can't drag anywhere. The move tool also doesn't work properly. I can click down and drag a layer, but after I release my click, the layer moves back to its previous position. The only way to move any layers is by free-transforming them.
You omitted the Options Bar.
Is "Always use Pressure for …" checked for any parameter?
