Drake has encountered an error on Schedule D

System freezes or produces the message "Drake has encountered an error....." when accessing Schedule D.

This can occur as a result of running low on system resources. Check available memory.

Go to task manager (press Ctrl+Shift+Esc on the keyboard) and check how many applications are running. This may occur more frequently on older computers. You may need to close some applications in order to free up more system resources.
