I'm using the "show in active : notice" option in mirc and notice something I don't really expect :

My active connexion is the server when the notice come from,
my active window is a query window, the notice is displayed in the query window (expected) and in the first common channel or status window if no common channel, I do not expect this since I just want the notice to be displayed in my active window, is this normal ?

Also, I think this is a bug :

I have flash for query option enable, if a receive a notice and it this displayed in a query window and mirc isn't the active application, it will flash.

did you try to use /remote off ?

In fact remote was already off when tested this.

Ok it looks like the first part it's normal, mirc always display the notice in the active window and in first common channel if exists or else in status window, right ?

Yes
