Can I suggest that when you tap on the Reports tab, the Filter dialog comes up before it starts crunching data for the report? I have 2 years worth of data, depending on what report I was looking at last it can take a minute or more before I can do anything again if I touch the report tab (but it no longer crashes... Thank you).
This way you could change your options, accept or just cancel if you didnt mean to tap it before it starts trying to work through all that data.
