Thanks for your response SASKiwi....answers below your q's:
Are all users impacted by this problem or is it just one or two?
All users of Excel where the SAS Add-In is installed.
What version exactly are you using? 8.1 or 8.2? Did you have the same problem with earlier versions?
8.1 Update 1 (8.1.1.3263) (32-bit). I dont believe so, no.
This type of problem is best progressed with SAS Tech Support as it will likely require turning on application logging and then analysis of these.
Yes, we may do that - elaborate as it is - first, before the effort, we need to know if others experience this problem; and if a non-SAS trouble-shooting log effort can fix it.
Do you know anything of this?
