From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.1a) Gecko/20020611 BuildID: 2002061104 With multiple tabs open, page up/down keys affect the leftmost tab page only, and are ineffective in the current tab. Reproducible: Couldn't Reproduce Steps to Reproduce: I've noticed this program twice in the past two days; I can't reproduce it intentionally and can't isolate a cause. I noticed that the page up/down keys weren't working when using tabbed browsing. Switching among tabs, I noticed that the keys were effective only in the left-most tab, no matter what tab I was actually working in. Opening a completely new window seems to correct the problem in the old window.
Reporter: your build is more than a month old. Please download the last nightly build and do a clean install (i.i. uninstall previous build and erase directories in "c:\program files\mozzilla.org\mozilla", except "plugins" directory. Most of the time, such a glitches happen because the settings from different versions are not 100% compatible.

>similar: bug 157233 Same thing, with the additional observation that the page up/down keys were affecting the fundamental (first) tab even when covered by another tab. Clean-installed 2002072108 and have been unable to reproduce.
