This issue can occur when multiple diagrams/tables are open simultaneously. To enhance performance, we recommend closing those you’re not currently using. You can easily close multiple items at once: simply right-click on a diagram/table tab and select the appropriate option from the close menu.

Additionally, ensure your Astah SysML is up to date and that your system meets our recommended specifications. If the issue persists, consider restarting the software.
