This should not occur inside the paint code as too much is already occurring there. The width could be disovered here and then reflected in the scroll bar during idle or timer processing. Scrollbar updating can be slow and has been the cause of noticeable performance issues in the past. > 2) Find is very slow if the codepage isn't UTF8: This is because > MovePositionOutsideChar() is very slow when it thinks the codepage might > have multi-byte chars, which is whenever the codepage isn't UTF8.

The code page should only be set when multi-byte characters are possible.

On GTK+, code pages such as EUC* may use up to 3 bytes per character. > 3) Rectangular pasting: > > a) If the clipboard contains a single line and there is a rectangular > selection (possibly zero-width), then the clipboard line will be copied > onto each of the selected lines.
