Saving Project Issues

After upgrading to latest version of SC I’m having occasional saving issues. one time ()out of 10) I see the messages SAVING APP and it never goes away. When this happens the toolbar icons are hidden and there is no access so it is very anoying. I also do not know if the App is already saved so I can proceed to other tasks. Of course this might be a browser or OS problem as well, but I’m using the same machine for years and never had that problem before. I wonder if anybody else experienced this ?
