Hi Pete, 
Sorry to ask a noob question but im having some trouble understanding WIDEFS and the integrated  buttonscreen I never used it before. 
I have the installation with two PC's, one running FS9 and FSUIPC/wideFS (latest versions of this page)  Both versions are registered. 
On the Second PC - I installed WIDEFS Client and opened up the widefs.ini file. I then pasted in the example of your PDF file (Page 7 User Manual), and after connection to the WIDEFSServer the button screen appears on the 2nd PC and is touchable (with a mouse) the buttons change color when pressed.  
All seams ok till there, but then i get lost, if i push as an example the Slew button it turns red, but on the serverPC (PC1 with FSUIPC and FS9) nothing happens. There is no interaction with the flightsim?  Even if i try to change it with the more complex example or even some small code line with only Slew as a huge button. Nothing happens on the sim 
Im running WIN_XPSP3 on the client PC and running WIN7/64bit on the Server pc with FS9 on it.  (I have treid with other software over the WIDEFS interface like a PFD/NDF of fightdecksoftware on the Client and there is no problem connecting to the SIM (FS9) with WIDEFS, there is communication between the two of them and i can see the moves i make via other hardware or with the mouse on FS9. 
So any ideas? 
Questions: 
1: Do i need to program anything on the FSUIPC/WIDEFS Server side to make thing work (Button screen) I need it as an Instructor station/button screen 
2: Is there a problem with WIN7/64bit 
Is there a noob in me? 
Cheers
