# Tool got stuck when opening from the Sandbox menu?

Sometimes docker based tools in the FinnGen Sandbox menu (e.g. CohortOperations, TVT, Lifetrack) get stuck when you try to open them from the tool menu.&#x20;

Your home directory (`home/ivm/`) may not have enough space to load the new Docker image. This causes the tool to hang instead of launching.&#x20;

To fix this, try:&#x20;

1. Opent the terminal Emulator inside your IVM
2. Run the following command to remove stopped containers no longer in use: `docker container prune`
3. Confirm when prompted (\[y/n]), then try opening the tool agian from the Sandbox menu.&#x20;
