The "Waiting for schedule time" bug *should* be now fixed 
in this beta-8.

The problem was a random hang during download causing the 
display of "Waiting for schedule time" or "Transferring 
data.." but WITHOUT any data actually being transfered 
(donwload rate was 0KiB/s). This bug was first diagnosed as 
a "display bug", but was later confirmed as being a "real" 
bug. It is also distinct from a previous bug, that was due 
to mishandling of keep-alive, causing hangs/timeouts during 
transfers.

Please upgrade as soon as possible if you are using 3.33-
beta series.
