Why is FM10 crashing when I change conditional text settings?

Question

When I go from "show certain conditions" to "show all" in some, but not all, files in a book, FM 10 crashes.
I've tried saving as MIF, then reopening, but it still happens eventually.
Sometimes it happens with the first file I open, sometimes not until after several files have been opened and
had their conditions changed, so it doesn't seem like a memory leak.

I posted previously under "[FrameMaker General Discussion] Internal Error 10024, 9332515, 9332572, 7278063". Log file has been sent several times to [email protected]. Last week, I sent many zips in separate e-mails of the entire project to Adobe Engineering Team for analysis (the project is too big to upload to Acrobat.com). No response yet. I suggested they need to test using a similar conditions as what I describe below.
BTW, I tried the above mentioned MIF wash (every single file of many book files), cut & paste to blank file, rebuild book from scratch, uninstall/reinstall FM10 ... all to no avail. I did trial and error (a shot in the dark) too: reset dictionary library, and choose other default printers (either Adobe PDF virtual printer or another physical printer on the network).  Nada.  No dice. It still crashes. I am not using Track Changes, so that is not likely a possible culprit.
I am running the latest FM10 patch on a Win7 64-bit HP Mobile Workstation. I have seen misc. posts online about FM crashing with laptops (Lenovo was mentioned), as well as unsubstantiated rumblings about laptop internal services or Adobe Flash or Adobe Acrobat X interferring with FM. Yes, I have many, many conditions present in book files; yes, yes, I have checked all source and target x-refs are in agreement for conditions. The only thing that works is to turn off All Cross-References in the Update Book dialog box. The book will update with that option cleared but crashes with it checked. It is definitely tied to cross-references and conditional content.
It is as if FM runs out of processing bandwidth or memory, both of which are impossible given the laptop has megatons of RAM and hard disk.  IT guy here speculated maybe Symantec Endpoint (security pak) is getting in the way, but that has not been substantiated; the process of removing/reinstalling this corporately mandatory security software is onerous and we are avoiding expermenting with it for now. It is disappointing Adobe cannot exterminate whatever gremlins plague FM. As a result, I cannot trust that FM11 is worth the expense (i.e. How can I convince the powers-that-be to approve the purchase when FM10 crashes like a plane without wings?).
I will post any response I get from Adobe to this Discussion and the other one previously mentioned.
