I uninstalled the 301601 patch. Way too much trouble. It hangs when you run a batch file. Then if it has an error and runs through anyway it loses the load cases and retains the recommended cases. Now when I run a file it says the tool bar has been updated do I want to use the updated toolbar. If I say yes then I get an error on batch run. If I say no it runs through ok.Again I am running the original Caesar II Version 5 with no patch now.
