Here is what I get when I do a format:
Microsoft Windows [Version 6.3.9600]

C:\Windows\system32>cd C:\Program Files (x86)\Flirc
C:\Program Files (x86)\Flirc>flirc_util.exe format
Warning: cannot open USB deviceFormatting Device, please wait... Done!
C:\Program Files (x86)\Flirc>
I just went back in to the software (v1.3) and it showed 3.3 but I force upgraded anyway. Shows 3.3. I think sequence modifiers was on before but now its not. I changed the interkey back to 0.
Sorry, I am not sure which key . . . when I use Plex the progress bar pops up then disappears after a few seconds. With XBMC a large box appears that covers most of the top of the screen and it only shows what appears to be the current time position of the movie . . . its not the normal OSD I am not sure which key causes that to display. Actually just playing with the remote, when I click the zoomlevel button the same popup shows.
EDIT:
ZoomNormal, ZoomLevel1, ZoomLevel2, and ZoomLevel3 on my harmony remote all cause this similar popup to show. I noticed that they are slightly different:
ZoomNormal displays 00:00:00/00:49:10 [00:00:47]
ZoomLevel1 displays 00:00:01/:00:49:10 [00:00:47]
ZoomLevel2 displays 00:00:02/:00:49:10 [00:00:47]
ZoomLevel3 displays 00:00:03/:00:49:10 [00:00:47]
I would have to take note what gets displayed on the screen to pin-point the exact key next time it happens. I am actually hoping I never see it again!
