FireFox doesn't appear to shut down completly when I quit, when restart it asked to exit FireFox eventhought it closed. When shut down computor error messeage comes up ' ns AppShell: Event Window end now and computor with shut down using 5.0.1


This happens after first time opened and closed. If I try to open from desk top, hour glass shows for a few seconds then goes away and FireFox doesn't open. If after opened once and try to use 'url' link for e-mail (outlook express) it doesn't open the link and ties up e-mail. Shut down computer and error box comes up 'ns AppShell: Event window' end now and computer will shut down.
