Thanks for the offer, but actually things are a bit more complicated
and include several steps :
1- the user selects different options on a modal stack
2- the user clicks a "search" button
3- various calculations are made client side according to the selections
and some data already in the main stack behind the modal one
4- a request is sent to a distant mySQL to retrieve text in a DB
5- data is sent back to the client (by chunks of 500 lines) and is
dispatched in different fields in the main stack
6- 1 field that contains the main text data has textstyle & textcolor
modified line by line and often several words can be modified in the
same line.
The whole process is quite fast, especially when using "lock screen"
for steps 3 and 6, but depending on the user"s selection and the
content of the DB, it can take 3 to 8 seconds at times.
And what I was looking for was a spinning gif throughout the whole
process from step 1 to step 6.
Unfortunately it stops spinning during steps 3 and 6 when using
"lock screen", which isn't very elegant.
Finally I replaced the gif with a progress bar which updates every
25 lines during step 6 (when more than 100 lines are returned) and
it's ok, since it allows me to use "lock screen".

How many chars in the text?
I'd wager that unless it's uncommonly enormous, you may find that the
one-time cost of writing a handler to use the styledText array of the
field will speed things up so much you may not even need anything more
than a brief watch cursor.
If you can post a sample project with text of similar length we may
have another good opportunity like the many forum threads we've seen
where long processes become brief blips with iterations from the
community.

Could you make changes to htmlText in a variable and then assign all
at once back to the field?
I thought of that, but it makes other parts of the script more
complicated.
Finally I will chose a different strategy : instead of an animated
gif, I'm
gonna use a progress bar that will be updated every 10 lines...
