AOL give me fits, at times, so I usually use another web browser. I know how frustrating it is so I try to keep Mike up to date on what's happening with it. Just know that he is aware of it and is trying to find out the cause.
Unfortunately, there really isn't a pattern to it, so it's hard to trace it . To me, it happens at different times and in different areas. Sometimes I can click on the last post (on the right) and I get an error message only to find I can hit the back arrow and enter through the forum and topics. Sometimes, I'm going along fine and reading, but it won't let me post. Sometimes nothing works. Even clearing the cache and history doesn't always work for me.
So, FWIW, we really are trying to get to the bottom of it. Meantime, I have found that Mozilla has worked about 99% of the time. If not, then Internet Explorer will. I have heard good things about others, but I haven't had the need for them .... yet.
AOL seemed to work fine yesterday and this morning.
