Your code is broke. There is no generic resolution for what you describe.
Maybe you have a handler for the back button action.
Maybe you have something happening on the page when it reloaded.
It could be one of 10,000 ways that your code threw an exception.
Good old fashioned debugging in this case. Start setting breakpoints in the most likely methods and walk through the code line by line.
