When I set the background color of code to be gray, it looks OK at this time. But when restart VS.NET2003, the area behind the code is write again, and the left is gray. It looks very uncomfortable. I use visual assist\\Visual Assist X 10.1.1301.0. Thanks!
My English is very poor, I'm afraid I can't understand your meaning correctly. Did you mean that you can't find where I set the background color of text? In the second picture, the left blue string is "front&color", the right one is "text".
I installed VS.NET2003-en over VS.NET2003-cn. Luckily, the problem disappeared even though I changed the IDE's language into Chinese. Thanks for all your help!
