This seems to be the same problem I reported about the file selection dialog.
(If I hid the file dialog when a file is selected with a double-click, it
froze and I couldn't select any widgets.)

This may be due to the fact that X automatically releases a pointer grab if
a window is hidden, and the CList widget isn't taking this into account. (?)
