trivolta Posted February 7, 2007 Share Posted February 7, 2007 I was worndering if you found a solution to this problem. Recently I got the same error. I happens for very long reports and as a result sevaral pages, beyond that point, get corrupted. Only the lines apprear and some random static text appears. It will be great if you could share your solution, if you got any thanks Link to comment Share on other sites More sharing options...
