| **Description** | **Workaround** |
| When setting up a custom calibration object, the last measurement entered in the the **Calibration Scaling** dialog is not applied and a message is displayed prompting you to enter or click outside the text box after adding the measurement. The object is saved as a non-scaled object; a corresponding scaled wand file is not saved and the calibration object does not contain a *Scale_X* annotation on the end. | In the **Calibration Scaling** dialog, after you have finished entering your measurements ensure you press Enter or click outside the measurement text box before you click **Save**. |
| When all the camera views are open, Shogun Markerless may drop frames processing. | Do not select all the Vanguard cameras to display in the Cameras view. |
| If you use multiple monitors to display Shogun Markerless, frames are dropped. | Do not display Shogun Markerless on multiple monitors. |
| If you run other software while running Shogun Markerless, you may experience dropped frames. | Do not run any other software while using Shogun Markerless. |
| If you activate and deactivate Video Calibration mode several times, Shogun Markerless may stop responding. | Restart Shogun Markerless before clicking Activate Video Calibration. Calibrate and reboot your system daily. |
