I found an old bug in bandicam. It has been around for a long time.
The computer does not enter sleep mode when idle system.
For example, after 30 minutes of inactivity (Windows system default settings) the computer must entered in sleep mode (hibernation), but it`s doesn`t work when bandicam is loaded (even if the recording is not in progress).
(This is very inconvenient because I need the application to start along with the system. Therefore, now (because of this bug) you have to start bandicam manually every time (which is very inconvenient) when you need to record the screen).
I am very hope, that this bug will be solved in next release of bandicam…
P.S. Windows 10 (20H2) x64 (with latest updates); Bandicam v18.104.22.1682 (latest)
