Lock screen and animated gif

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".
