Description Regina Henschel 2004-06-11 20:17:21 UTC
The attached document 'oneformula.sxw' contains 1 formula, which was generated
directly in Word processor. Doubleclick the formula to edit it. Make sure that
in 'View' the 'AutoUpdateDisplay' is enabled. Now delete the minus or make any
other tiny change. It takes about 20 seconds until the text in the document is

I then opened the same document in StarOffice 6.0, don't change anything but
only save it under 'oneformula_viaSO60.sxw'. When you open this file in OOo1.1.1
and edit the formula, the text in the document updates after 2 seconds.

My system is relative old, a 350Mhz with 128MB RAM.

MRU->TL: The Auto-update lasts for about 20 sec when using the attached sample
file. This could only be reproduced on Windows 98.

Reproduced with OOo1.1.2 on win98se.
And: loading oneformula_viaSO60.sxw into OOo1.1.2 is very much faster than
loading  the original oneformula.sxw file !

Is it really the word processor, which causes this problem ?
It looks more like a problem of the component,which creates the sxw-files.

Workaround: who could write a script/addin, which converts OOo.sxw to SO60 and
back to OOo.sxw in order to increase the efficiency of the screen-autoupdate for
maths-formulae ?

btw: saving the original file as oneformula.sdw (SO50) and reloading it in
OOo1.1.2 does not help :-(

Settin component to "formula editor" in order to find this issue with Math
specific queries.
