Description goodguy00@zoho.com 2021-10-15 22:10:58 UTC 
Description:
i have a document >500 pages. because it gives performance problems (at least on my 4 core machine) i had to subdivide it by chapter into smaller pieces. then i made an overall master. now only the master has performance problems, ie to update the master it takes like 2 minutes. so far so good.
that means, there seem to be timing problems inside writer. when i drag an inserted document in the master navigator, to update the new sequence it takes writer several (long) seconds. during that time, i'm able to grab another inserted document and reposition that one, but then writer crashes. (ok, workaround is just not to do that)


Steps to Reproduce:
1. create 20 documents of 20-30 pages each, create master to include all of them
2. in the master navigator, grab one and reposition it. if you have a "slow" machine, it takes writer >10 seconds to quiet down
3. during that time, the navigator is not modal, so you can grab another document and reposition it

Actual Results:
swriter crashes

Expected Results:
the navigator window should be modal and forbid actions.
alternatively (which i would prefer) the master should only update, when i tell it to update (tools>update all), so it would not take time to resequence


Reproducible: Always


User Profile Reset: No

Can you attach sample documents (e.g. a zip file containing all of them) to simplify reproducing this?
Comment 3 goodguy00@zoho.com 2021-10-18 19:22:01 UTC 
ok, i spent some time on this. answer: yes and no. same document base (because residing on a central server). tested 5 clients with (in my opinion) same software base. 2 work fine (cannot reproduce) 3 don't (there writer crashes reliably). created fresh users for this. i'm puzzled.
as this is not really bugging me, i will retract it. i thought, there is more behind it ...
