I tried getting support for this on Opera and Adobe forums, but without responce. I also submitted bug reports to Opera and Adobe, also with no result.

In short, when I have either only one non-english keyboard layout enabled, or more than one layout with at least one non-english, I get problems typing non-english text in flash text fields in Opera browser. I'm also having difficulties typing English text too, depending on the sorting of keyboard layours. More details here:

Thread on Opera Forum

Any ideas anyone?
