Hey you might be wondering what I am going to talk now. Yup its about oracle Apps front end look and feel. Some of the users still using same old grey and blue looks and DBA wonder if he missed something. No not at all, just check these two profiles and you are done.
Change the following profiles at user level first-
"Java Look and Feel " to oracle and
"Java Color Scheme" to blaf
If it works for you then change it Site level to have others enjoy the same.!!!
Keep Troubleshooting !!!
