After developing web pages for so long, and as a web user for a long time.... Sometimes we start to overlook the simple things.

For example;
A user sent me a screen shot stating the colors were messed up on a set of textboxes on a web form. After a few minutes confirming the CSS, I looked at the screen shot again. All the text boxes had a yellow background.

The answer was also right there in front of me as well, but as complacent as I was, it didn't hit me until the 2nd look. The Google toolbar was also installed and the autofill button was lit up. Ah the answer to my question is there in the options.

The fix is to have the user turn off the yellow color highlighting as shown below.
