I've experience this bug for at least 1.5 years: If the mouse is clicked in the timeline of the Matrix or HyperEdit (but NOT the Arrange) for more than an instant, the SPL rewinds near the beginning. This means that I definitely can't do MIDI scrub in the Matrix or HyperEdit, but I also have to click the mouse button with a very press (sometimes I exceed that time by a microsecond and all hell breaks loose). This happens to me with LAMP 3.5 - 4.04 on at least 5 completely seperate computers (all with variations of PT/TDM hardware - I don't know if this has anything to do with it). f-erenc "Without chemicals, he points"
