Re: Crash when displaying Req. in Req. tree (QC 9.0)
I can't offer any help, but would point out that I suspect IE8 is not supported for QC v9.0. v9.0 was transitioned to Limited Support in March 2009, which means HP stopped creating patches for it. IE8 was officially released in that same month. I suspect that no patches were created to ensure QC v9.0 would work with IE8.
Have you tried using the IE Compatibility View mode, so that IE runs virtually as v7 when accessing QC?
