Kels, any chance you'd consider changing over from HashTab to HashCheck? http://www.ktechcomputing.com/hashcheck/ You're already using his OpenCmdPrompt extension.......
The notice of the update was in Jeffs blog...... http://blog.codesector.com/2008/08/02/teracopy-20-beta-4/ Look for post #19 and a few previous ones complaining about crashes and such like. Thanks for the addon update!
Gorki, Jeff over at Codesector had to do a silent update of 2.0b4 to take care of some program crashes when transferring large files. The installer for 2.0b4 was updated on August 5th, the day after you updated your addon.
