Each track has two tracking modes: auto mode and pin tab mode. Auto mode is enabled by default. In this mode Otsledit tries to check the web page in the background, if it is impossible to check the web page in the background, it tries to check it through the attached tab. But there are such websites when in auto mode to check the page does not work. In this case, the track will go into a non-working state. Then you need to track immediately through the attached tab.
For such cases it is necessary to enable the pin tab mode. For each mode you can separately adjust a check interval using the sliders.
