BR LiveSlice - A couple of oddities

[DarkStar]

Slice preview
- I loaded a loop (booty(90)) and the first slice did not preview properly
- it sounded like it had an Attack value set for it?
- I reloaded the sample from the browser, still muffled,
- I closed LiveSlice and eXT, reopened both and loaded the sample again,
- this time the first slice previewed OK.

BPM refresh
- I loaded a sample and the BPM was calculated as 0 (that is - a sensible BPM could not be worked out),
- when I selected another loop already in the Loops panel the BPM was not recalculated. It stayed at zero,
- reloading the loop from the browser calculated the correct BPM.
