Sorry--didn't see this myself after upgrading to OS 10.2.6. Check what vendors the file is coming from, or try searching and downloading some files you've never tried before. You're using LW 2.9.11, right?

A few more ideas to rule out your system as the culprit:
1-safe boot and repair permissions (a good idea after installing any software)
2.-reinstall Java
3.-test with a new admin user (this entails downloading and installing a fresh copy of LW)
4.-wait till the weekend (recent LW updates have come out Friday nights)
