Is this a bug?---sometimes I can't get rid of a particular search result window-no matter how many times I click on the "X". And although I have set prefs to allow 10 searches at once, after I have, say 5 search result windows, as I say-I can't get any of them to disappear, and new searches I try to initiate don't show up after I punch "search" on the left. Bugger it! What am I doing wrong? Or is it not me?? Help!
