After updating to 10.7.4 from 10.7.3, TextEdit and Preview won't launch. The icons bounce for a few seconds and then nothing. Have tried repairing permissions a few times but with no luck. Disk space is not an issue (300 GB free on 750GB HD). Disk Utility reports nothing unusual with the startup volume; "verify disk" checks out fine.
Any solutions? It's driving me crazy. Thanks.
