The biggest problem I have is being able to force it to occur, then force it to stop.
Here's what I DO have so far:
- It's add-in independent
- Sometimes rebooting fixes it (temporarily)
- Exiting Excel and restarting it doesn't fix it.
- It almost always happens after my initial boot-up, but not "reboots".
I work in a corporate environment and will log off my PC at the end of the day, but not shut it down. Often while I am gone (over the weekends, etc), the corporate behind the scenes servers will push updates and they may or may not reboot the PC, so when I come to work in the morning, I don't know what state the PC is really in, whether waiting for my initial log in after a reboot, or just logging me back in. I can usually tell after I log in, though, because if it's a reboot login, all kinds of server scripts start running.
This morning, I did a rebooted login, and Excel was experiencing the pseudo-random code breaks. I call them "pseudo-random" because Excel will halt at the same lines on functions that are called repeatedly, but from day to day those lines will change. I got fed up enough to attempt a reboot and Excel seems to be running OK so far with no interruptions.
One difference between the initial boot-up this morning and my re-boot. Some of the bootup scripts that the server runs only run on the first bootup of any given day. I think the culprit lies within one of those scripts since the corporate scripts often re-apply the
same updates over and over again. It's like they don't trust their systems to have updated Office the first time.. or the second... or...
I'll keep checking on this, but I suggest since a reboot usually clears the problem temporarily, the problem is external to Excel itself (though is probably still a bug in the code somewhere).
I guess I could run ProcMon next time it happens to see if I can trap the culprit.
If any of this info helps, please let me know.
