This may not belong here but perhaps someone would be willing to confer with me off-list?
After Scite re-install with new MkIV instructions I can not find where to change background color. (I was able to change it before under ebswift installation although syntax highlighting for *tex did not work--such a deal!)
The only lead I have so far is, commenting out "import lexers/lpeg" in SciteGlobal.properties takes away all highlighting for all languages.
I know there is a warning about lexer interaction from November 2011, but I have not had any other problems (except Purge All does not work) with Scite 3.02, lpeg lexers 3.02-1, and ConTeXt ver: 2011.12.20 22:24 MKIV.
