figure* env sliding out of page margin

[gabs1234]

Not sure if I'm doing something of-the-heretic-style, but getting some weird behaviour from figure* env when using some big subfigs (with widths bigger than .5\linewidth).

Not sure if this is related, but margin figures also run out of the page. They then have to placed manually to be visible completely.
