How do I disable card cover switch

Do what the pros do...use a card reader.

either get a card reader to hook up to your usb on your computer this is easiest and dont have to download a driver for your camera if you dont have a disk. Or just get a usb for your camera and download them.

One way to transfer photos from your Olympus c-4000 camera to your computer without installing any software is to remove the memory card from the camera and plug it into a card reader on your computer. The pictures on your camera will be shown in windows explorer as a removable storage device.

If you don't have a card reader connected or built-in to your computer for your memory card type, then try connecting your camera with the usb cable, and your pictures will show up in windows explorer as a removable storage device.

Here is the link to the Olympus store website where you can purchase smartmedia cards.

First of all you need to be sure you are using a memory card that is an Olympus card. If it is a non-Olympus card then the panorama option will be disabled to you.

Then go to Menu - Mode Menu - Camera tab - Panorama option and select right arrow. This should enable the panorama mode for the camera.

Unfortunately the only memory card that can be used in this camera is a smartmedia card. The largest smartmedia card available is a 128mb card.

There is usually a small tongue on the card cover that engages either a switch or some other device to detect if the cover is open.
Check that it is not broken or that the sensor is not damaged etc.
Hope this helps...

The flash is malfunctioning and causing the camera to not work, the flashing lights in the viewfinder is the camera indicating the malfunction. Most likely it is a board that needs repair and that'll cost a flat rate minimum $160 from OLY.
