I'm sorry. I made a mistake at the problem description.
The reproducution procedure like this:
class CTest
{
p // In the class scope, when i input a single "p", the auto suggeestion listbox appears,
// and it includes several lines such like "public:" or "protected"
// However, if i select these items which have a colon at the end, the problem happens. The auto indent does not work.
// if I input all characters manually, there is no problem.
};
The setting file was sent.
