If the user selects to show only those posts, say from the last day, and then selects another time frame before the script has finsihed displaying the results of the user's first choice, an error is generated.

It doesn't scare me, but it might be of some concern to the less-computer-savvy user.

Perhaps, there might be some more friendly message for the user instead of error messages like:

Server Error in '/' Application.

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Yep, that's your typical ASP.NET growling response. The bark is a lot worse than the bite. Of course, it you wouldn't be so impatient Wabbit! [:)]

Seriously, we can customize responses, but perhaps I need to make a list of the recurring ones before I go crazy trying to track em all down. I think it will be a pain to do so.

BTW, thanks for all of your feedback during the development phase. I sure do appreciate your help.
