Intermittently, I have run into problems were I am unable to modify or delete files ('Access is denied'). Sometimes, rebooting solves the problem, but the problem seems to move to different files. In other cases, a reboot does nothing. Using ProcessExplorer, I found that exalead had locked these files. Closing exalead allowed me to modify/delete the files. I am running Exalead one desktop Free 4.6.0.504. 335606 408949
