Autoupdate currently only works with portable versions or when Wieldy is run with user which has administration rights. I did not had the time yet, to implement a better update mechanism, which downloads and runs the setup.exe file.
You have set the Recuring Action Type to Recurring (Subsequent)?
Did you set "Create in Advance" to greater than 0? If so, then 1+the number will be created.

Else you may have found a bug. Does it still happen?
Can you please tell me which synchronizer you want to use? So i can help you with configuring.
Unfortunately i don't speak portuguese so i would need your help.

I can send you an xml file with the english translations and you can change them to portuguese translations then. After that i can include the language with all future releases.

Just let me know if your willing to help me. Of course i will give you the credits for this.
It only works with 2007, 2010 and 2013. Support for older versions will not be implemented.

Mainly this is a framework issue, or better said how Wieldy uses the framework. But there is a solution to speed up the startup time. I will try to fix that.

Wieldy does not contain a mail client, but it can handle contacts and calendar entries via synchronizers. I already have a working caldav and carddav synchronizer, which also should work with google. Unfortunately i did not had the time to finalize and release it yet. This feature is scheduled for the next release.
