I'm struggling with zooming with the mousewheel. Was very frustrated in v2015, hoped it was just that version, but also in v2016 and 2017. Most noticeable when I zoom out and then try to zoom in. However, only happens sometimes, while other times, just stops working. Could not pinpoint what scenario was exact cause.
I have a number of graphics programs, and it doesn't happen anywhere else.
I did contact Tech Support, but got nothing to resolve it. I have searched here and elsewhere online, but either I'm not seeing it or not finding it.
Specifics, if that makes any difference: Win 8.1, Logitech Click! optical mouse, Logitech mouse M705
I have the same issue on my Windows 10 PC and Painter 2017. The mouse (Logitech M705) scroll wheel will start working in only one direction of zoom. I also found that setting the touch ring to Scroll on my Intuos 4 Wacom tablet zooms in much finer steps than Auto Scroll (but keep the speed set to the middle). However, when Jeremy Sutton tried this on his Mac it worked better with Auto Scroll/Zoom.
The only problem with using the Scroll setting is that zooming in and out is reversed on the touch ring.
Here we are in 2021... and we still have that same problem. I was just about to report the bug, when I thought to check if others had reported the same issue. Thank you for the Wacom touch ring tip. That's a useful workaround.
