I noticed this in v8.0 - 8.103 and opened a thread over there but since it is happening in 8.160 I thought I would mention it here. I hope that is alright. I'm going to use a link instead of retyping everything.

I can't see why I would be able to use other flash reports using the same Open Flash tool you are using. There are images in the link.
Thanks and sorry if I should have retyped the issue. [:$]
