I suppose this could be something I've done, but I was playing and in the middle of the match the toolbar just up and dissapeared without warning (where you have the commands) I was curious A.) What causes this, and B.) how can i fix it, I tried everything and the only thing that got close was holding down the right click, that brought 6 buttons back but they disappeared after you used one of them 

tried that and it took and brought everything else back

the klingon is without the right click held down, the fed is with the right click held down, you can see the tiny build box in the corner.

I tired to toggle the X button but it wouldn't line up like the original button bar / tooblar.

a full reinstall seems to have fixed it but anyone know what could have cuased it in the first place?

If I blow it up again I'll hand over the config files  but I was just in the mood to play  where are they by the way? I am pretty sure I can recreate whatever I did (8 player map lots of dominion troops on the map had to have been clicking something in a retarded manner)

looking through the top level cfg files (rt_cfg etc) I didn't see any values the game used that would point to the position or the placement of the box, there were several notices for the toolbar/menubar but there was no actual values that would point to it being on / off whatever. If nothing else we can assume that its a configuration related value.

ah I see them now
 well I don't mind playing with those values, I'll see if altering one of those will reproduce a similar effect but it looks likes its a game of adding something to throw it off rather than subtracting (as it just recollects the data anyway and then throws it back out)
