first i'm gonna say something on the typing when NO syntax highlight
yes, it's slow in the latest svn...,the problem is that wxscintilla's scintilla version is too low, in scintilla 1.65, it did a lot of optimize...(the latest version is 1.72).
After change wxscintilla's scintilla to 1.72, CB solve the problem when NO syntax highlight.
second, when ya turn on the syntax highlight, CB is still slow...
the reason for this is still unknown,but i'm sure it's the problem of the editor lexer algorithm. now i'm trying to fix them...
