lock screen password overwrites when connecting remotely
I am new to OS X, and Macs in general. I have a new Mac Mini (purchased April 2013). it is running OS X server, version 10.8.3. I upgraded it to 16 GB ram, and opted to get a bluetooth Apple Keyboard and Magic Pad.
Issue:
Everything works great, until I use any kind of remote connection. It doesnt matter what software I use - VNC, logmein, or Screen Sharing - everytime I connect to it I am only able to type one to three characters before they are automatically highlighted and overwritten with my next key stroke. I have tried connected from a PC, MacBook Air (2012), iPad 3rd generation, and an iPhone 4s. Each one has the same problem. The only work around I have is to watch the screen as I type, and use the arrow keys to move the curser to the end and continue typing. After several moments of careful typing I can log in, and then everything is fine. I do not have that typing issue any other time, only at the lock screen.
Ideas?
Thanks for your time and any asstance you can provide.
