Geopak looses connection to the gpk in the middle of work

Geopak looses connection to the gpk in the middle of work flow. You have to get out of the file and get back in to get it to see data in the gpk.

Line styles disappeared again. If I was using Geopak this would have also brought on the loss of the connection to the gpk file. Only way to restore is to get out of Microstation and restart.  This is not normal.
