.x-dlg-mask, invalid value for opacity

[ssapq]

I see the following selector:
.x-dlg-mask{
background-color:#CCC;
display:none;
left:0;
opacity:0.5px; /* this should be opacity:0.5; ? */
position:absolute;
top:0;
z-index:10000;
/* and one would want to include these: */
-moz-opacity: 0.5;
filter:alpha(opacity=50);
}

Otherwise, the .x-dlg-mask was not showing as transparent. I don't see a config option, so I assume one sets this in the ext-all.css.

Did you open it in some kind of editor? This is what I have and it hasn't been edited in quite some time:

.x-dlg-mask{
z-index:10000;
display:none;
position:absolute;
top:0;
left:0;
-moz-opacity: 0.5;
opacity:.50;
filter: alpha(opacity=50);
background-color:#CCC;
}
