First thing to try is to remove your Aperture Preferences. This fixes a lot of interface irregularities (and seems likely to fix your problem). Directions are on the Apple Aperture trouble-shooting page.
You might make a list of your prefs in order to recreate them. Note that none of your Presets are in your prefs, so you don't have to worry about losing/recreating them.

- I reformatted the card several times since.
- I only have one card, so I cannot tell if it also ocurrs wth other cards.
- I close down Aperture several times a day to free up resources.
But I did not reboot my entire machine, I hardly ever do. I just did, and it solved the problem.
