1) When the miner freezes, the system error window appears.

But the SRB-Miner process is still in computer memory.

The SRB-Restarter utility thinks that the miner is working. But the miner is frozen.

Perhaps this problem can be solved on Windows 7.

It is necessary to disable the output of system notifications.

 gpedit.msc-> Computer Settings -> Administrative Templates -> System -> Internet Communication Management -> Internet Communication Settings -> Turn off Windows Error Reportin
