I just updated to v. 2.3.8 on a new laptop. I opened the sample file (ST-Sim-Sample-V2-3-8.ssim) and did a short test drive. However, I got a long error message when I tried to “Export All” the Probabilistic Transitions to an Excel Workbook. The error message was titled “Unhandled thread exemption. More information” with many lines thereafter. I have a screen shot I can send via email if that would be helpful. Thanks for any help or suggestions. Greg
