I'm in the lab with office locations and plant occurrance areas but...I can't leave the office, I keep getting told I should leave everything as it was, otherwise Wang will be picking on me again. I've tried going back and redoing everything but still can't leave.

I can't pinpoint what you might have missed but try:
- checking your inventory for anything that can be returned on the work bench like evidence bag or instruments.
- check also all the machines you used and see if you left something in there; microscope, scanner...

Thanks, I'll try all of those things, I'm getting a bit claustrophobic in Wangs lab. Copper

I've tried puting bags and tweezers back on the work bench, they won't go, I checked the microscope was turned off and the scanner was empty.short of going back in the game even further than I have already, I'm stuck (in the lab and in the game)!! Help SOS mayday.....

I don't have a save for this spot, Copper, but there are some at this site:

AOM save

Thanks Rushes for the info, I went to this site and it seemed that I had to download more than just a saved game (toolbar etc..) so I was a bit worried about that. If anyone has a saved game for this part of the game that would be great. Thanks Copper

I'm still stuck in the same place, I've gone back to the bomb and started again, I still get back to lab with both photo copies of locations but cannot leave the lab. I've followed the walk thro' to the letter but every time it's the same.Can anyone help??? Copper

Say "no" to any other download stated in that site.
Just register and then download the saved game file.

I did as you said and at long last I'm out of that lab. Thank you. Copper

Have fun.
