The thing is, on my old HTPC (also Zotac) it worked just fine with an HP IR receiver and MCE remote with IRSS. The new one has a built-in IR receiver, and IRSS has problems with that as well as with the old HP IR receiver. Installing IRSS disables remote input altogether.
I had IRSS (Test Build 1.5.0.62) and Translator set up with my old zotac mini pc (running Win7 x64), MS MCE remote and an HP receiver and all was well. I got a new mini pc (same OS) with an IR receiver built in and when I install IRSS on this new PC the remote stops working. I set it up the same...
I have the same problem (though I'm using translator to run XBMC). The "force focus" button just unchecks itself and I have to use the mouse to put the focus on the window after I launch the program.
I just installed build 1.4.2.3281 in the hopes that it would fix it but no luck...
