I am testing a feedback activity and each time a user submits their answers it jumps to a blank page (in IE6), which loads for around 10 seconds +, then finally jumps to a successful submission page.

I enabled the Debug messages: Show errors, warnings and notices setting,  but no warnings were displayed

Just wondering why this process is so slow? I am worried that most users will think the ssite breaks at this point as there is nothing on screen to say what is happening...
