I've installed Proteus 8 and began to work with it. I've built a primitive circuit with oscilloscope. At first time visualization window (with graph of signal) was being got. I closed this window and stopped the simulation. But in the next time this window didn't open.
I try to solve this problem with the help of Google and found the answer: "You must to click right button of mouse at oscilloscope and find "Digital Oscilloscope" and problem will be solved". But it actually works in another versions of Proteus. I didn't find this in Proteus 8.
How to solve this problem in Proteus 8?
