I remember having this issue once but I'm not seeing it now in IE8.
As for responding, I've seen questions that have later resurfaced even though they've been marked as Answered but have new questions posted to them. Skimming for 0 Replies messages would skip these. When I come I open the forum and skim the Titles with an eye on the Latest Activity. Once I hit the morning of the previous work day (thus Friday if I check the forum on a Monday) I stop because I know there are going to be no more 'new' postings after that date/time.
Interesting Toby, that works. Each of us have our different ways of finding questions to answer. Jonathan once mentioned that he looks for questions that have several responses but don't have the green answered mark. That way he's most likely to find the more difficult questions. I'm on the other end, I look for "0" answers because I don't want new posters to think they've been ignored and go away and never come back.
That makes sense. I'm not as experienced with the software like Jonathan nor as caring like you...wait, that came out wrong...
