Never ceases to amaze me how many different problems FS9 comes up with to annoy me each time I fly it! Another new one today...When ATC gives me an instruction, the ATC window closes as I click on 1 or 2 or whatever to respond. I have to re-open the window before I can reply (e.g. when transferring to another ATC sector). Annoying. Is this a setting in fs9.cfg or elsewhere that has gone awry, or something else? From 2002 until yesterday, I never saw this before, so why now when I start FS9 this morning? I sometimes think my PC hates me!!! :((BTW, I will get RC5 when it comes out, possibly FPE before that, but until then would like to fix the FS9 ATC if possible!).Thanks,Martin

OK, sorry, ignore this post - found out the cause (my own stupidity - and an incorrect keyboard shortcut setting).
