I think this is caused by the fact that at the first connect, the GUI resets 
the board, and the connect eventually will fail. The second connect successfull 
since it does not resets the FC. I investigated this problem a lot, and it 
seems this is a limitation of the .NET serial library and/or the fdti drivers. 
I recommend the go along with it (also try 2.2 since it more allowing for 
connect timeout). For nail down that this is the real issue with you, try 
disconnect the DTR line on your serial connection. This prevents the reset.

I'm using a usb serial port so I don't think I can disconnect the DTR 
line.  Is 2.2 compatible with the Multiwii 2.1 code?

Nope, but you can try the new 2.2 MultiWii.

Actually it works the same way with the MultiWiiGUI. After powering up the 
usb/serial converter (usually an FTDI chip) the first connect always pulls the 
DTR and causes a reset. Apparently it's an FTDI driver issue... The 2.2 WinGUI 
tries to wait and retry till the FC ends the restart.

The WinGui beta does work better and I decided to try your suggestion to 
upgrade to MultiWii 2.2.  I saved my parameters using the WinGui beta 
and then uploaded the MW2.2 and all was ok.  I tried to load my 
parameters and it takes forever.  Am I doing something wrong.  Should I 
load the parameters and then connect?  I did that once and got an error. 
Should I reset before i do the load parameters?

You cannot move parameters between 2.1 and 2.2 all PID scales are changed, also 
there are significant changes on the checkbox items. You have to clear EEPROM 
and retune with 2.2.
