All windows that have a left-right scroll bar scroll to the right continuously whenever the mouse is over the field (even if another window is active)
This usually only occurs if the mouse is stationary. If it’s moving at all, it doesn’t happen.
The effect occurs in Google Spreadsheets in Firefox and Chrome, in a file browser and Libre Office Spreadsheet.
The effect occurs regardless of mouse motion in Firefox.
If I hover over the tabs in firefox it shifts over to the next tab to the right until it gets to the right-most place
The effect doesn’t occur if the mouse is moving
It doesn’t occur in Firefox
If I press “ctrl” in Firefox the browser zooms out.
The effect doesn’t occur in Chrome
I can’t drag windows. The cursor turns into a hand, but then turns back into a cursor within a fraction of a second. Sometimes I can move the page in little steps before it happens.
I can’t resize windows. The cursor changes into a drag emblem, and it doesn’t change back, but moving the page does nothing.
I can still drag objects on the desktop.
