Firstly, look at the HTML in both cases. Use 'view source' or equivalent 
in both browsers; and/or save the HTML from each browser to a file and 
then compare the files.

If the files are different, then you need to work out why your 
application is sending different data to different clients.

But if the files are identical, then my suspicion is that you are 
generating invalid (X)HTML - and therefore one of the browsers is 
processing it differently to the other.

For example, you might have mismatched start and end tags in your 
template. Or it might be that one of your select options contains a HTML 
special character, since you're not escaping them. That is,

    <%=  @start_choice =>

should really be

    <%=h @start_choice %>

Similarly, your html_select helper should be escaping the options in the 
array.

I'd use the tool xmllint under Linux to check for well-formedness. There 
are probably other options for Windows. At worst you can upload the 
content to an online checker service, or you can parse it in Ruby using 
REXML::Document

From your posting subject line, I'm not sure what is the @data that 
you're talking about, but as for "bug?" - yes, it probably is a bug in 
your code.

Good luck,

Brian.
