Usage Issues

Red pop-up messages usually occur for three reasons:

If the message Script run-time error: Stack-Heap Collision appears, it indicates that the script is overloaded, exceeding Second Life’s limits. In this case, click the Split Script button in the top-right corner of the script display interface to split the script into multiple files. Then, add these scripts to Second Life one by one.
Incorrect software configuration, leading to improperly generated scripts.
If the configuration is correct and red pop-up messages still appear, it means you have enabled EnableDebugMode in the Begin node. This option outputs debug information during script execution and is not needed under normal circumstances. It is only required if you are a developer performing secondary development and need to view debug information during script execution.
