We are also experiencing this issue, and the product is unusable for our whole staff. Enterprise 24 R15_69. Clearly was an auto-update as several DLLs in the program files have a timestamp of this morning and no intentional updates were applied. Each computer is touching/locking over 1000 files/folders in the Attach directory constantly. Support has been less than helpful and barely acknowledges the issue, but supposedly, the 'backend team is working on it'.
