Ok, I tried it on another machine and the crash was back. Very weird how its fine on some machines and not on others. I used a library called Caliburn for dependency injection to implement an MVC pattern, I don't know if that's the cause (not much error detail to go on), but today MS released Unity for Silverlight which is another inversion of control/dependency injection framework. So I'm going to try changing it to use Unity. Maybe that will solve it.

Hi Greg,

I just updated it to use Unity and Prism instead of Caliburn. Now it doesn't crash on my 2 machines. Can you clear your browser cache and try again to verify its fixed? I don't know if it was a problem in Caliburn or a problem in the way I was using it, but I like Unity and Prism better already.

Note that the Execute Query button does not work in IE, it throws errors. There are 2 methods in google gears that I can't get to work in Silverlight using IE, but they work fine in Firefox. The 2 methods broken in IE are GearsResultSet.GetFieldName(int fieldIndex) and GearsResultSet.GetFieldValue(int fieldIndex). I can get the field value if I know the field name ahead of time like GearsResultSet.GetFieldValue(string fieldName), so for most applications I should still be able to use Gears even in IE because my field names will be known ahead of time. Unfortunately for the query tool we have no way of knowing what fields will be in the result of ad hoc queries. So the query tool will only be usefull in Firefox, but for other features I should be able to use gears wityhout any trouble.

Best,

Joe
