Created a drop test, ran for 2 days. Process window is gone, no star.exe process running, yet when I open the file, SW still thinks it is being solved. Can't do anything with the study parameters and there are no results.

I have shut down the computer a number of times yet it seems under the impression the study is still being solved.  The only way to stop this is to use the simulation cleaning utility which deletes everything and the study would need to be set up and run again, which has been done twice. This has happened on plain old static tests also.

Anyone run across this before?
