We have developed several crystal 7.0 reports on a Win 98 os and have found that some of them act very strange on an Win 2000 system. for example: 4 of our reports the page size has been racked all out of kilter. Two of our other reports cause GPF's on Win 2000 but operate fine on 98. Does anyone have a clue as to why and maybe some other pitfalls we may look forward to? Thanks in advance
