I don't think any of the developers is a telepath. Translation: Your mail is 
ridiculously low on detail.

Your best bet would be to install a profiling tool like sysprof, and then come 
back with additional information, such as your hardware configuration, which 
applications were running, what were you doing at the time, etc.
