Here's some more information, which may (or may not) be useful to you about my recent issue of MBAE 9.3 "ignoring" its exclusion list. For what it's worth, my IE10 has crashed 3 times in the past two days since I updated MBAE to 9.3. I'm not saying that MBAE was necessarily the cause... it may be completely coincidental. Event Viewer asserts the faulting modules as being ntdll.dll, comctl32.dll, and mshtml.dll in these 3 instances. Since my IE had been relatively stable until just recently, I decided to test things (temporarily??) by reverting back to MBAE 9.2.1200. The exclusions data file that was updated under version 9.3 survived the uninstall (9.3) / reinstall (9.2) process... and when I then accessed Lotus iNotes this morning, it did NOT object to the .dll file there! Expressed differently: while I could not create the exclusion under version 9.2, 9.2 WAS able to acknowledge/use the exclusion created via 9.3. In contrast, while 9.3 allowed me to create the exclusion, 9.3 itself was unable to acknowledge/use it! Does that tell you anything useful? UPDATE: When I tried again this afternoon, 9.2 likewise "overlooked" the exclusion, and blocked the iNotes .dll. Most perplexing.
