In a virtual, computer-based laboratory system, what kinds of issues or errors do you think you might find to be weird, unrealistic, inappropriate, or even incorrect within a virtual lab when compared to a real-life lab experience?

One thing that will be weird and incorrect is that there will be no physicality. In the physical world, accidents happen: people fumble things, mismeasure things, get distracted and break things. In addition, there are perceptual changes that occur in the real world that may not be accounted for or may have a different effect in a virtual world. For instance, due to refraction, an object seen partial through a beaker of water and partly through the prevailing atmospheric air (without the beaker of water in front of it) will present an optical illusion whereby the portion viewed through the water appears larger and closer than the other portion. In the real world, this is an interesting optical illusion but in a virtual world, it may take on significance that doesn't correspond to a real-world perception of it: its significance may take on dimensions that do not correlate to real world experience.
