There are similar posts to this (in other sections), but i think i have found the issue and wish to report it to the dev team.
in a nutshell, i reinstalled windows and all of my programs/apps. when in Audacity, i was trying to scroll through a song, using the horizontal scroll wheel on my Logi MX Master 2S mouse. the scroll bar was moving, but the track was not. if i manually clicked on the scroll bar and moved it right or left, the track would move. also, when i held down shift and used the scroll up/down wheel, i could scroll through the track.
before uninstalling Audacity, i uninstalled my mouse accompanying app (Logi Options Plus) and tried again. this time, the horizontal scroll worked correctly and i could scroll through the song. to check, i reinstalled the Logi Option Plus ass and the issue came back.
i have contacted Logi and reported the problem. but the support agent said, that it was more likely to be an issue with Audacity and not with the Logi Options Plus program. as i previously mentioned, others have experienced this issue, but didnt state which mouse they were using. they may be using a Logi mouse and have this program installed.
can someone please look into this issue. as i cna no longer use the Logi Options Plus app and customise my mouse as i wish.
specs
OS - win11 24H2
Adacity - 3.7.4
Logi Options Plus - 1.92.731496 (latest update - 2025-06-20)
