It is possible to pause the capturing of the user actions from the Run sidebar. Once it is paused the user will be able to operate with the application under test or with any other not relevant to the test application and none of his actions will be captured.
There is also an option to minimize Sprinter by pressing keyboard Ctrl+Backspace keys. Clicking on it again should get Sprinter back to normal size.
When there are many screen differences detected by HP Sprinter, only a summary view appears in the difference viewer, indicating the total number of differences detected, but all the differences cannot be viewed.
Displaying a summary view of the differences detected, when many differences were detected, is product design.
To fix this issue, you can set the "MaximumDiffNumberToReport" parameter in the settings.xml file (Path: %appdata%\HP\Sprinter folder）.
Set the value to around 5000, and reboot Sprinter.
You should be able to view all the differences detected.
