If you use the pull down menu's (used in Bugzilla for the "OS" selection) you will notice that clicking and dragging the side bar or playing with the arrows will end up "selecting" the text within the choices as it would look if you selected text in a textbox. It looks strange!

Reassigning to Rod.

This is definitely happening on NT and Linux. To use some terminology, this is happening with <SELECT>s with SIZE=1, but not with SIZE > 1. The wierd highlighting happens when the arrow at the top and bottom of the form control's scrollbar are clicked on, or upon vertical mouse movement anywhere in the scrollbar area after a click anywhere in the scrollbar area (WinNT) or Click-dragging anywhere in the scrollbar area (Linux). The highlighting has no effect on what is SELECTED, but the same items that were highlighted when a selection is made are still highlighted when the combobox is dropped down again. To see that this isn't affecting <SELECT>s with scrollbars of SIZE > 1, visit enter_bug.cgi and play with the "Component" form control. Tested with: 1999-12-25-08-M13 nightly binary on Windows NT 4.0sp3 1999-12-25-08-M13 nightly binary on Redhat Linux 6.1 (gnome+enlight) Additional Information: I'm sure I've seen this before... is this a regression of a FIXED bug, or a DUP?
