Diacritics in LATVIAN still has a bug

I use MacOS 10.6.8, with Intel MacBookPro 1.1

Some months ago already wrote (see quote), hoping Scrivener update might fix it, now downloaded 2.2 - bug still is here.

To reproduce it, you have to swich language preferences to “LATVIAN”, and try to get out those strange letters like described below.
So now I need to just type everything in another text editor, then just copy, paste.

This is not convienent.

Special character with quote mark (diacritics).
I use Latvian in Scrivener (MacOSX), for getting our special characters like ā, ē, ī, č etc in key combination like “quote mark” key, then characters key (or quote+character) .
So in Scrivener I often get -‘Ada- instead of -Āda-. Often means about 10%.
This almost never happens in any other applications (may be 0.5%).
Funny thing is - I can not get it out intentionally. By making pause between two keys longer or shorter, or like.
