Just thought I'd mention, I've been using esupport via Safari for windows (beta) for the last few weeks and so far, haven't run into any difficulties with the app.
In fact, the quality of the rendering (not sure that's the right term), the way the fonts look, the way the interface and buttons are presented etc. is (to me at least) much easier on the eyes than either IE or FF (which I also use at different times) Pages seem to load faster as well.
Overall I'm very impressed!
The only niggle I have found (and according to the support forums, they are looking to correct this in a future version), is, the forward and back via mouse button don't work.
Anyone else try it? Just curious what others experience has been.
Cheers,
Rich
