hi guys.
Help with a problem.
when I run a miner in the pool, I am closing gridcoin Wallet(gridcoin-qt.exe).
start production in solo no such problems.
gridcoin Wallet can work from 30 minutes to 12 hours, and close.
Ran through the console and a separate mining cgminer-3.7
the problem is at work in the pool.

sorry for the bad translation, do not know much English.
