I have updated my McCLIM CVS working copy with the latest commits since last January 11. In the CLIM Listener, when I left-click the current directory presentation in the wholine pane, I get this error: Type-error in KERNEL::OBJECT-NOT-TYPE-ERROR-HANDLER: 39 is not of type XLIB:GCONTEXT [Condition of type TYPE-ERROR] Restarts: 0: [ABORT ] Return to application command loop 1: [RETURN-TO-LISTENER] Return to listener. 2: Return to Top-Level.
