One more try on vtkImageReslice crashes

[Sathya Krishnamurthy]

Hello All

Sorry my mailer sent it before I could complete it.

Anyways, the crash occurs exactly after I have done two rotations ..i.e
used ImageReslice twice and the crash occurs at

vtkImageReslice::GetMTime ()

Kindly someone help me with this issue.

Thanks

Sincerely

Cheers
