I seem to have lost the ability to drag and resize the ATC dialog window.All other aspects of RC4 and FS9 are fine.I've touched nothing,honest.

I just tested the FS9 version 3.990 I have installed. You drag the window by using the left mouse button only in that window title bar area. You can drag any edge of the entire ATC window for vertical or horizontal sizing. After doing this be sure the FS window has tha main focus so RC and other programs receive keystrokes.From the FSUIPC History document in the Modules/FSUIPC Document folder:"The size and position of each open FSUIPC display window (eg. for Radar Contact or the Lua display) is now saved in the FSUIPC INI file whenever the window is re-sized, moved or closed. Previously these details were only saved when the window was closed by FSUIPC (i.e. by Lua or the application or the "AdvDisplay" hotkey) or its state was changed (i.e. docked or undocked."

Ron.Thanks for replying.Before I posted yesterday I realised I was just .01 0f a version adrift with FSUIPC so I installed the latest version but didn't get round to trying FS9 afterwards.For all the time I have owned RC4 I have been doing exactly wht you describe in moving and resizing the ATC window.It's never been a problem until 2 days ago when I just couldn't get the PC to "focus "on it.I've just this minute tried FS9 with the very latest FSUIPC and all is now as it was.I can't believe it was a version change that did this(or was it) so if it happens to anyone else it seems a re install of FSUIPC might be appropriate.Or was it something else in my PC?As I said,I touched absolutely nothing in the settings of anything.
