Just run thus code it will be obvious....

What is "bew"?

I assuming "new".

I just read the script breaking modifications on the new 3.3.14.0 version.

I think the mouse floods the messaging system with mouse messages and keeps AutoIt from Idling the CPU, and therefore it runs the script  at full speed.

Strange thing is that it produces the speed boost no matter if the cursor is in the Autoit window or not.

The slowdown really is too slow to make the scroller convenient to watch.

I see your speed change behavior on my 32-bit Windows 7 Pro SP1 with Intel Core i3 @ 3.4 GHz CPU, running AutoIt 3.3.14.5. Speedy when script GUI has focus, not speedy when other windows have focus.

I don't know how to fix it, but I wanted to report that it's not just something on your machine.

I do notice that adding a Sleep(10) command just before the Until... line alleviates the issue quite a bit. Not perfect but at least the text doesn't go supersonic in the scroller.

It does go quite fast does it not!  And sleep(10) makes it go too slow.   I want to adjust the delay built into the GuiGetMsg() function.   Maybe there

is a byte that we can edit so I can get slow mode to go faster.

From the Help file: 

In the OnEvent mode instead of constantly polling the GUI to find out if anything has happened you make the GUI temporarily pause your script and call a pre-defined function to handle the event.

Take a look here.

Give it a try :)

Use a Timer to check how many times per. second your graphics update:

New Information:  After about 25 minutes, the overspeeding caused by the mouse movement stoppend and it ran at normal speed again.

I have ran the script at least 3 times and at about 25 minutes the scroller behaves normally.  Very odd.

The scroller , when running at normal speed, is  really too slow due to the complexity of the script itself.  I do not want to slow it down more that it is.

I would however like to speed it up.  Decresing the dwell time built into the GUIGetMsg() function would do that.

I will try AdLib to update the graphics and let you know.

The Adlib function fixes the mouse speeding up the scroller  problem. That is very cool.

The  scroller behavior is not real smooth anymore. And when I imbed it in my other script it is really really slow.

The GuiGetMsg() loop is really slowing this process down.  As stated above, A Do Until Loop makes the scroller  run

very fast , and I can limit easily with with a TimerInit().  But then I do not get the Message Loop.  I need a way to make the CPU Idler in the

GuiGetMsg()  function not restrict the speed so much.  Maybe we can make that function adjustable or something.  I did notice that the CPU ran at 13% when

it was in a Do Until Loop, and 6% when in the GuiGetMsg() loop.  There seems to be alot of room for speeding it up.

Really?  How does that solve this problem?

Really ? what about letting the attitude go, start thinking for a little bit and properly answering that question?
