Juan, I've had a couple of instances where documentation of scripts 'freeze,' where they can not be scrolled or searched, etc. It occurred with new LFHH and today with ImageSolver. It doesn't happen initially, but eventually. Not sure if it's after application of the script, or just opening/closing their help file a couple of times. Closing the tool doesn't fix it, only a full close/reopen of PI does. Thanks- hope you can replicate!
