So I have a strange issue that I'm taking a stab in the dark out here with this question. We have built several forms in sharepoint for use on mobile devices, specifically blackberries. Unfortunately, on occasion, when the user takes an action that posts back, say hits a button to move to a screen to view/edit a row from a repeating table, the browser just go blank. Refreshing seems to have no effect, so the user has to close and reopen the form losing any data they might have entered. I did witness this once, and my gut instinct would be a connection issue, but I wanted to reach out to see if anyone has experienced this and might have come accross a solution. Thanks
