I seem to have somehow lost the ability to select individual verts in the UV editor by clicking. When I click the mouse the cursor becomes a paintbrush even though I am not painting anything! I can select verts using border select or A key only. Individual verts selected in the 3D window are highlighted just fine in the UV editor.
THis happens whether I use plain unwrap or unwrap from view etc etc. and whether or not the verts are selected in the 3d view.
Please advise me! :o
