Hey everybody! First time poster, long time reader on this forum!

I seem to be stuck in the lab, I can't leave because Nicole keeps telling me "I should leave everything as it was, otherwise Wang will be picking on me again". I just analyzed the seed and the box wrapping. I have the two maps printed out and in my inventory. The scanner lid is closed, I have the tweezers in my inventory and I can't put them on the worktable or where the microscope is, it doesn't seem to be an option. The microscope's light is turned off. I can't remove the sample from the microscope, again that doesn't seem to be an option either. The box wrapping is secured in a plastic bag in my inventory and I can't leave it on either tables.
I have no idea what to do, I've tried everything I can think of but nothing works. Nicole refuses to leave the lab. I've read the two walkthroughs on here, followed them through and neither address this problem. I also checked out the walkthrough that came with the game and there is no mention of leaving something as it was before I exit the lab. I'm about to give up on this game because I can not progress. So, this is my last hope. Any suggestions? Has anyone had this problem?
