Short description of error
The Ctrl-C lasso select function works only intermittently.
Exact steps for others to reproduce the error
I switched the Select Box option to Select Lasso and it didn't work. I went out of the window and came back in and it did work, once. Now it's not working again. All the other selection options work.
Based on the default startup or an attached .blend file (as simple as possible).
