Good afternoon.
It seems has begun after any last update SD +.

The problem consists in the following: At the answer to the request, the answer does not go and on the screen there is this window.

It happens some times in day.

If the error is not observed at the answer to the request, this window appears for a second and is closed.

Picture with a window in attach.

We use SD + 7.6.0 Build 7602, the error is observed on the machine of operators with Windows 7 x86.
