Happened a couple of times, but not sure if its always. If you are actually watering when a tutorial or report dialog pops up (tutorial help, or first dead plant notification etc), the watering can get stuck in permanent pouring position... led to me overwatering until i realised.

Luckily a single click elsewhere on the screen returns the watering can to normal.

Other than that, i'm loving this. First time round i over-crossbred, and ended up with delicate plants in basic soil. Second time round, and i'm green-fingered

BTW, I'm away for the next 2 weeks. Is there a file i can transfer to my laptop so i can keep looking after my plants while I'm away?

Yes you can take a saved game anywhere you want.. First, pause the game. Then go to My documents\LDW\Plant Tycoon\ and copy your save game.. Your first game slot is PlantTycoon1, so if you started it in that slot copy that file and send it to the other computer. Then when you are ready just install PT on the other computer and paste your savegames into it.
