We have a workstation which has been doing drill downs recently. We've got the SP4 of the newest Evo installed. Since that update we now get btrieve error 3006 every single time a drill down button is pressed. Any time any drill downs are done we get the error.

I don't know that anyone has tried it on other machines (we dont have that many users). I'll give it a try.
 
Also, even though we get the error 3006 it still works. It's strange. You get the error and then the drilldown popup window pops up anyway.
