Cheers for the update bud

Installed & it seems a bit faster than 1.0.7

Staying at 1.0.7 for the moment (after having tried this one, as well as all its RC's, both under windows and linux). Reason: It still has performance issues (more obvious under Linux, but existing under windows as well).
Even for opensource software, newer is not necessarily better.
Same applies for the mighty Firefox 1.5: while the Linux version works pretty decently, the Windows one has a nice memory leak (obviously enough not spotted neither by IE users, nor by Opera ones- one out of two Opera releases has a huge memory hole due to bad QT3 implementation!), which has not been corrected, so far.
