InRoads SS2 - corrupted .alg file with ProjectWise CONNECT

We are running InRoads SS2 v08.11.07.615. We have Alternate Workflow checked on. We are using Project Wise Connect Version The .alg file is set to Read-Only. The user will check-out the file in InRoads and check back in after changes are made. Our .xin file is set to Read-Only for the Geometry.

From time to time without warning our .alg gets corrupted and empties out all alignments. We cannot figure out why this is happening. We scramble to find the latest .alg file on our hard drives and restore it as best we can.

Users open the .alg file as a single open while others use a .rwk file.     

Any thoughts?
