Two problems here. Totally wrong forum. Even the windows on a mac forum isn't really appropriate for this. Something like this goes on a forum dedicated to BioShock like a forum on a site like ign.com (i'm sure they have a bioshock section there) or, even better, on the game publisher's website.
Second thing is that you need to be a little bit more specific about the problem. You click the mouse, then wait five seconds, and then it takes the picture? Or do you click the mouse, then it takes the picture, then the game freezes for 5 seconds....
or do you take the picture and then you see the picture come up on the screen but you can't do anything for 5 seconds.....
If i remember correctly, when I played the game in bootcamp I would click the mouse and it would take the picture immediately, then the game would hang for about half a second while it loaded the picture, and then it would show me the picture I took for a couple of seconds.
Now, you're not a horrible person or anything just for posting this in the wrong forum, but it bothers a lot of people
