Zooming very erratic

[RhB_HJ]

Zooming in 5.11.3 is very erratic when using Ctrl+Mouse wheel.  What gives?

[vistisen]

I have tried to see how it operates for me, It seems to be fine on my system ( windows 7 64 bit, logitech performance MX mouse using the standard windows driver) each 'click' during rotation of the scrolling wheel steps on zoom level up or down using exactly the same levels as I get by clicking on the plus or minus buttons. Is your scrolling wheel working in other applications?

[BritsTukker]

I'm using a Logitec mouse under WinXP(SP3), and its one step of the wheel for one step change in the zoom level consistently.

[RhB_HJ]

Still not its usual self, but zooming and scrolling works normal in all my other apps.

It seems erratic to me as well, but I tend to click on the +/- buttons rather than use the scroll wheel. When I do use the scroll wheel I often get no reaction, so I scroll again, and then suddenly it's scrolled too far, hence my preference for the buttons. I'm using a standard Microsoft mouse with standard Windows 7 interface.

And as long as we're on the topic, I'd still like to see the zoom increments have more steps, as I've suggested before (this time putting a few specific steps back into the list after David explained why they were there) here: http://www.anyrail.com/forum_en/index.php/topic,2024.0.html:

5:1    4:1    3:1    2:1    1:1    1:2    1:3    1:4    1:5    1:6
1:8    1:10   1:12   1:14   1:15   1:16   1:18   1:20   1:21   1:24
1:25   1:27   1:30   1:35   1:40   1:45   1:50   1:60   1:70   1:75
1:85   1:100  1:125  1:150  1:175  1:200  1:250  1:300

I'll go with alex's post. Mine has been doing that since 5.10.1. About half of that is my system's inadequacies, but that still leaves a little room to call it an area that's got room for improvement. Given the sluggish response of many video systems, perhaps zooming needs to have a higher slot in the stack(?)...

[RhB_HJ]

It used to work flawlessly until this last update. Certainly not caused by my system, it does NLE with great speed, no delays. And all the other programs work as usual.

[David]

What do you mean exactly? That zooming continues after you've stopped using the scroll wheel, or that it reacts slowly?

David.

[RhB_HJ]

OK here's what it does our doesn't do. Normally Ctrl+Scroll wheel would smoothly zoom. Shift+Scroll wheel usually would go left or right, smoothly. Now it does at times and not at others. However I found if it fails and I then click on the corresponding control it will recover on work as it should. When zooming it also has a tendency to not follow the increments that it should when turning the Scroll wheel e.g it will follow the commands, then hang, next take a big jump.
Only started with this last update.

[Jeff]

Yes, that is the behavior as it works for me. And it doesn't just hang once, but intermittently, I think as the speed of the mouse wheel being scrolled. This is what I have seen happen since about version 3.2. Normally, when you tell me that it's been fixed, I can stop worrying and get back to design work. This time, it didn't quite fix things.

[santerdam]

Zooming works smoothly for me. Also the left-right scroll works fine. I do notice that those actions take rather much power from your computer.
My PC is rather powerfull with a dual-core processor and plenty memory - some zooming can easy boost the system to a 50% load.

Sometimes I notice a certain delay in actions. This is when the autosave is writing a copy of the AR-file.

PS : Most actual version on Win XP.

Nothing changed really for months concerning zooming.

However, it's a tricky thing.
On one hand, you want it to be instant and smooth, on the other hand it should stop whenever you stop using the scroll wheel.
As the redraw can be slower than the mouse wheel with complicated track plans or slower computers the program tries to find a balance here.

The fact that we still have so many XP users and people that run it using Wine on Linux or Mac doesn't help either. This restricts us very much in using the full power of the CPU (multithreading (Wine) and advanced instruction sets (XP)).

On our test machines zooming works fine in most cases, but of course when it doesn't work well with the whatever you work on, you will notice it all the time. So please send me the layout file that causes most problems and hopefully I can find some further optimizations.

Hi David,

The Capt's revised home layout does it, too.

Not for met it doesn't, perfect scrolling no matter how fast or slow I spin the wheel on a three year old PC

[RhB_HJ]

I doubt that it's my computer, only happens in certain AR files.
