I have applied custom master page on my website and since then my rich textbox icon images are repeating like mess
i m having custom application page and all my rich texbox icons get messed up since when i deployed master page. master page deployed successfully and there is no other issue.
background-repeat: no-repeat;is missing, have you tried inspecting the elements and look at the styles? Some property might be overriding the original one (from v4) – eirikb Sep 20 '12 at 14:43
