Description ken 2016-08-21 18:46:41 UTC
I'm using Windows 8.1.

I have two monitors.  If I put Writer on the second monitor and then do anything that opens another window, it appears on the first monitor.

For instance, click the down arrow next to the highlighter, the menu appears in the upper-right corner of the first monitor.

When creating a table, the table dialog appears on the first monitor, in the middle towards the left.

Help, About also showed up on the first monitor when I opened it to put the version in this bug report, in the middle towards the right.

Note that it does appear to remember where the window was last displayed, as I moved the Help, About window, closed it, reinvoked it, and it was in the place I had last moved it to.  So that is likely related to the bug.

Perhaps it needs to have an array for "last position", the size being the number of monitors.  Then, it should only check the last position of the monitor that Writer is currently being used on.  If empty, do the default -- for the monitor that is in use.  Then, save the value as before, but in the array and only for that monitor.

Hi Ken,

Thanks for reporting.
Working on Ubuntu with Unity, I see / have seen some unexpected behavior too, now and then.
Not sure if that is the OS or LibreOffice's fault.
Ciao - Cor

Confirmed with v5.2.2.2/Windows 7.

Not every dialog opened on the 1st monitor, for example Insert Table dialog didn't (but About did), but then when I later opened it with the main window on the 1st monitor, it opened on the 2nd.

I don't reproduce with highlighter and table dialogs, but I do with Print and About dialogs. 
Tested with OO, behavior seems better so not fully reproduced. Only Styles and Formatting dialog is separate if undocked, but Print and About dialogs open where OO is (if on second monitor). Similar with LO 3.6.
Repro starting from 4.0. Repro now with 6.3+.
I'll mark regression.
