Windows – Adobe Reader plugin for Firefox steals touchpad scrolling input

adobe-readerfirefoxscrollingtouchpadwindows 7

When a PDF file is open in Firefox 4 in the Adobe Reader plugin, I am unable to scroll using the touchpad multi-touch gestures in other pages in the browser. Instead, the scrolling input is stolen by the Reader plugin; when I try to scroll on another page, the position in the PDF document changes in accordance with this scrolling input instead. This problem causes me to lose my place in the PDF file when I do other browsing, and I cannot scroll as easily in other pages because I must use the keyboard instead. However, I am able to scroll with a USB wireless mouse using the mouse wheel. Why does this happen, and what can I do to work around this problem?

My system is a custom-built HP Pavilion dv6z-3000 Select Edition laptop with Windows 7 Home Premium x64 Service Pack 1.

Edit: The problem may to be related to whether focus is on the plugin, but I'm still not sure why Adobe Reader would steal only scrolling input from the touchpad and not any input from any other device. Any suggestions?

We're looking at the bug here in this thread. If you happen to have this bug, comment with your OS version (Windows 7 64-bit, for example) and with who makes your touchpad.

Hopefully, we can debug this sooner rather than later. :)
