Finer control with mouse wheel (Windows)

Lightroom is so much about speed of execution, and I would be even faster if it allowed me to use the mouse wheel to move sliders in the Development module effectively. Right now the mouse wheel moves the sliders in increments/decrements that are too large. E.g. slides for Recovery, Black and Fill Light go in steps of 3, the Brightness sometimes in steps of 9 sometimes of 10, depending on its current value, contrast in steps of 5. It is too coarse. All those slides should go 1 by 1, for fine tuning; color temperature should go, say, 100 by 100. For brisk adjustments I can already drag the slider or input a value.

Did you check the settings in the mouse driver software in case something has changed?
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

Cant scroll horizontally with mouse wheel in FF

I cant scroll horizontally in FF unter XP+SP3 by pressing the mouse wheel sideways. This is the same in FF 3.6 and 4.0 beta, while in IE 6.0 and in other MS programs (Explorer, Word, ...) it works fine. I am having this problem with 2 different mice: Fujitsu 400NB and easytouch ET-9600. I cant find newer drivers for them than what I have installed from the CDs. Here some settings from my FF: mousewheel.horizscroll.withnokey.action;0 mousewheel.horizscroll.withnokey.numlines;1 mousewheel.horizscroll.withnokey.sysnumlines;true. Some time ago I played around with them but that didn't help. What else can I do to get FF scrolling horizontally?

Why am I unable to scroll through bookmarks with mouse wheel anymore?

Used to be able to scroll through bookmarks with mouse wheel, now I am unable to. I have tried reinstalling firefox and disabling all addons but same problem. Please help!

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

How to remove a black border box that continously tabs to each field automatically till end of web page; restarts to top of page, cannot stop this box. Scroll bar cannot controlled with mouse, returns auto to top of scroll slide, never remaining at bottom

how to remove a black border box that continously tabs to each field automatically till end of web page; restarts to top of page, cannot stop this box. Scroll bar cannot be controlled with mouse, scroll bar returns automatically to the top of scroll slide every time I move the bar to the bottom of the scale. Also, there's a rectangular text box (with black background and white text) that is always on the desktop that emulates a typed text, HTML, or cmd function.

Also, there's a rectangular text box (with black background and white text) that is always on the desktop that emulates a typed text, HTML, or cmd function.
The first two problems (box cycling from element to element on page, scroll bar returning to top) can be caused by a stuck (or defective) Tab key on the keyboard. Such damage can be caused by a liquid spill; just one tiny droplet is enough to short a wafer switch under one key.
The last issue (black box, white text - sounds sorta like a debugger window) I haven't seen, but could be caused by something similar.
To check for that, try using a different keyboard. If you're using a wireless keyboard, turn it off and see if the oddities stop.

Jumpy scrowl control with mouse.Only with Firefox, not Internet explorer. Problem fixed when I updated to 6. 0.2 but problems returned after about a week.. 0.2

Jumpy scroll wheel control with mouse. Only with Firefox, not Internet explorer.Even pushing the scroll wheel and trying to adjust for a smooth easy scroll the text stops and starts. Problem fixed itself when I updated to 6. 0.2 from an older version but the problem returned after about a week.. The problems go away when I go to web site and scroll but is back when I return to my home page (mozilla firefox)

Good post, and glad to hear you had a solid transition. Mine went well too, though I think I beat the rush.
It's worth noting that the vast and overwhelming majority of headaches people were experiencing were related to download and activation servers (as well as credit check servers for some mobile carriers) being crushed and overwhelmed.
To give you an idea of just how crushed, here are some numbers. In the last year, something in the neighborhood of 8 million iPhones have been sold. That's just shy of 22,000 per day. So the typical traffic is around 22,000 times a day, someone is hitting the server for update/activation.
This weekend, Apple sold 1 million iPhones. In other words, 333,333 phones per day. Holy crap!
As if that wasn't enough, there are 8 million of us out there with the first generation iPhone. Not only do we need to download the new firmware, but we have to install it. The installation process requires hitting the activation server again, to validate the phone. Mind you, not everybody upgraded this weekend, but a few million did. For the sake of argument, we'll assume that's 1 million a day. So, instead of the normall traffic of 22K phones a day, those activation servers got SLAMMED with 1.33 million activations per day.
It ***** that some people had delays and hiccups and a hard time and everything, but completely understandable. With luck things will run more smoothly from here on out.

Horizontal scrolling with mouse wheel?

I have built a website for a client that scrolls only horizontally. Is it possible to scroll with the mouse wheel horizontally?
Is there certain HTML I need to add?
Thank you

Hi,
There is no out of the box solution to force horizontal scrolling with mouse wheel. However, you can add your own code to your Muse site after exporting it. These docs should be helpful :

Ae 13.1can't pan in viewer with mouse wheel button !!!!!!

one of the bad things in ae 13.1 is that you can't pan in viewer with mouse wheel button

In all honesty though, even if fixing this kind of bug would create a new one, its not a bug that should be ignored. Its a major one imo (fix this bug and create a new one, I would personally take my chances). I remember after effects had a bug in a recent update, were audio always was set to low quality when you export, which was very annoying, and it wasn't fixed for months! This bug is worse, and happily I read this thread before updating so Im staying away for now, I hope it won't take months to fix this one.
It makes sense and Im really happy to hear a chunk of the AE team is working on optimizing the code.Though I think they should devote more people to that. AE is such an old program that I assume those working with keying or other of the features that have been updated lately, they bought a better plugin for it allready. I would much rather have NO updates for a year if that means the program would become more stable, faster and in the future they would not need to patch up layers and layers of old code, as you say....and from what I remember the response from the community was pretty much the same from every single one when it was asked in public what people wanted in the future updates....a faster program. THe content of AE is all ready great, and you can get plugins for pretty much everything you need...except optimization and an up to date software that uses the computer to the maximum potential.

Scroll with mouse wheel requires multiple "ticks" to start scrolling

I recently got a new mouse, and now when using firefox the scroll wheel doesn't want to work correctly. Everywhere else I can do single scroll ticks to scroll content, but in firefox a single tick scroll is just ignored as are multiple ticks if done somewhat slow. In order to get firefox to actually scroll with the mouse wheel I have to quickly do a few ticks at once. Doing so makes for very inaccurate control.
I've tried turning off smooth scroll, hardware acceleration, and pixel scroll, but none of those helped. Any help getting firefox to stop ignoring slow and single scroll ticks would be greatly appreciated.

Did you check the settings in the mouse driver software in case something has changed?

Scrolling with mouse wheel in column browser starts from the start of the list

Hi, I'm wondering if anyone else has been encountering this problem with iTunes.
Ever since updating to 10.5, whenever I use the mouse wheel to scroll in the column browser, it starts from the start of the list, regardless of which artist or album is highlighted.
For instance, I press the M key to jump to artists starting with M, then use the mouse wheel to scroll down the list, in iTunes 10.5 it jumps me back to the As.
The strange thing is that if I then use the mouse wheel to scroll down to the Cs, then jump down the list via a key press, mouse wheel scrolling will start me back to where I last scrolled (C).
How can I fix this problem?
I'm using iTunes 10.5.0.142 on Windows 7 Home Premium.

I can confirm the behaviour. It would seem iTunes is keeping a separate record of the position in the list for use by the scroll wheel, and then snapping to that before scrolling up or down a screenful. The same random jumps happen if you use the keyboard Page Up/Page Down commands and then use the mouse wheel.
I shall file a bug report.

Issue with Adobe Muse parallax jitters with mouse wheel scrolling vertically.

Hi all,
I'm learning Adobe Muse for the first time to put together a wedding website (http://mattandsangeeta.businesscatalyst.com/index.html), so bear with me as I'm a novice at the software - though I do have the most up version, Adobe Muse CC 2014.
So far, it's been an excellent platform, and for the most part the site functions incredibly well. However, one key flaw I've noticed in it is the parallax scrolling speed when using a mouse.
The parallax portion of the site jitters badly, and while we've found a few improvements for the issue (the best was making sure there was nothing that had scrolling set to "0"), I'm still at a loss for how to get smooth scrolling transition speeds. Every forum Adobe has seems to be showcasing the features, and not troubleshooting this particular issue. A lot of posts are similar, but none seem to be resolved. I've noticed that other parallax pages are smoother with the mouse wheel scrolling down, so I'm hoping it's just an issue with Muse that has a setting or snippet of code that can remedy the issue.
What makes me realize it's the mouse wheel scrolling, and not the site itself, is because whenever I access the site on my surface pro tablet, the parallax runs buttery smooth with touch control or even trackpad control. Same when you click the middle scroll button and pan down. Without any mouse wheel scrolling, it looks great! But with a mouse wheel, it hiccups constantly and ruins the effect.
So, is there any way to smooth out the steps that the mouse wheel scrolling seems to be causing?
Thanks in advance,
Matt

Thanks for the link, however that specific thread was one of the ones I referenced in my original post.
In the beginning of the thread, it's clear that coding can fix the issue, though it's not recommended. More telling is that the response you referenced indicates that the issue is claimed to have been either fixed or mitigated In updated releases of Muse.
As you pointed out earlier, however, Firefox displays the parallax a little better than Chrome, and much better than Internet Explorer. I'm assuming that Adobe Muse Creative Cloud 2014 release attempted to this issue.
So my question kind of remains: am I missing a setting that would make the scrolling more smooth, or is it simply just a limitation of the browser / software / parallax combination?
Thanks again for the responses.

Fluxbox mouse wheel window shading patch

Hey all, i was an avid kahakai user (a wm) and really enjoyed shading my windows via the mouse wheel. I recently switched the fluxbox, and the damn thing doesn't have a way to configure mouse binds outside the source, so i wrote a patch to have fluxbox let me shade and unshade my windows.

Screen smooth scrolling with mouse wheel

I have a screen with a number of vertical sections that are initially all collapsed. After expending these sections the screen becomes too tall and I get a scroll bar on the right. Scrolling it by dragging a scroll bar has expected smooth scrolling but using the mouse wheel scrolls why too large portion of the screen.
Any idea what to look for?
Thanks

No, I do not have other parts installed. I saw this behavior by others last week in the Safari forum here at Apple too. They wrote about this could be happend by using fast user switching and only Safari 4 was effected. But now, as I saw this after upgrading to Safari 4.0.2 in Aperture too, there should be a biger bug elsewere in the System or maybe Webkit?

Is it possible to disable scrolling of tabs with mouse wheel?

Often I close tabs using middle mouse button which is also the wheel. When I point cursor on the tabs, wheel accidently rotates and I close wrong page tab.

You can't disable the tab scrolling with the mouse wheel AFAIK, so you need to use other means to close the tab.<br />
You can close the current tab with the close X on the tab or one close X at the end of the tab bar or use the keyboard with Ctrl+W.<br />
Not selected tabs can only be closed via the right-click context menu as an alternative.
Otherwise you can try to set the minimum width of a tab to a larger value to have more room with the scrolling.
