Snap to grid: Error Message

When snap to grid is enabled I very often get the following message:
"Points that you can snap to are outside the current view"

That message appears when IntelliCAD expects input for a point and the mouse cursor leaves the current view (only when snap to grid is enabled / F9). When it happens this message is on the screen for at least 20 seconds.

In the second line of the message there is ".... no points are available inside current view". This is definitely not true.

Do I something wrong?
How to disable this message?

Thank You in advance
