Hi @mirmalag
Thanks for posting here, and sorry for the trouble. As I mentioned in my previous reply, there is a bug in macOS Sierra 10.12.2 causing the AppleScript we use to enter mixed case characters improperly (only after any character that would regularly require using the shift key – i.e the capital B in your first example or the @ symbol in your second two examples). We’re current beta testing a version that includes a fix for this issue. Would you be willing to try it out to ensure that it resolves the issue for you?
In addition, we made some modifications related to Secret Agent improperly entering values when using certain international key layouts – This is what was included in the 3.1.5 release. Unfortunately, because of the aforementioned bug (unrelated to this modification) Secret Agent is current improperly entering values.
That fix is outlined in this post: Odd secret agent paste behavior
Shoot me a PM, or write into support@zetetic.net and I can provide you with the beta version to try out.
Cheers,
Micah
