Following good advice from this forum I just upgraded by browser to IE5 and Chat now works perfectly
(and I now have the voice facility in Yahoo Chat – great fun!).
Only downside is that IE5 overwrote my old mail programme (my BT one, not the one I use for PPRuNe) and now I have to use bloody Outlook Express. In old versions of OE it is possible to switch off the preview pane but I can’t find the same facility in this version. Any ideas?
