Why does the Address Book insist on placing itself in some oblong spot at the bottom of my screen every time it's opened? Could it, perhaps, remember the last place I dragged it to, or at least center itself, when opened, on the screen? Thanks, in advance!

It opens to the center of the main mIRC window for me. Dunno why it's behaving oddly for you.

Perhaps it's my resolution, 1920x1080? Not sure why that would hurt mIRC's centering abilities, but maybe it's a start.

I also have a HD monitor running at 1920x1080 and the address book always opens top left for me.

Seems like saving the last position would solve the problem though
