Problem

Observer XT becomes unresponsive or hangs when a user attempts to open a project or import FaceReader data, particularly when the import includes a Detailed Log.

Details

Affects Observer XT 17 when importing FaceReader data. The Detailed Log option in FaceReader exports contains a very high volume of data, which can cause Observer XT to hang or stop responding during import. Hardware issues are typically not the root cause.

Solution

1. When importing FaceReader data into Observer XT, **deselect the Detailed Log** option in the import dialog. The Detailed Log contains a high level of granular data that significantly increases import time and memory usage.
2. Attempt the import again without the Detailed Log. This is sufficient for most behavioral analysis workflows.
3. If the Detailed Log data is required, consider importing it in smaller segments or on a machine with higher RAM.
4. If Observer XT is already unresponsive with the project open, force-close the application via Task Manager, reopen it, and attempt a fresh import without the Detailed Log.
