Thanks Arvind,
Note 1938659 does look exactly like our issue. The note mentions that ADAPT01711393 would be resolved in BI 4.1 Sp2.1. Unfortunately I applied patch 1 and it did not fix this defect.
1938659 - Error: "Access is denied" occurs when viewing Analysis Workspace document using Opendocument through SAP EP on I.E 8
I am pursuing issue with SAP OSS. Ugh
