Firefox window will not adjust in size, the window is either Maximized or no window displays.
Environment is Windows XP Professional. Opened Firefox (3.6.8) and an icon displays on the task-bar, but no window.
Rt click on icon and options are "Maximize" or "Restore". Clicking on either produces a full locked window. Cannot re-size or drag by top bar.
Clicking on the "Maximize" icon in the upper right corner of the window and the window disappears. Window may be reopened by a Rt click on the task-bar icon and selecting "Maximize" or "Restore"
Opened another session of Firefox at the same time, and a small window (as small as it can be) appears in lower left corner. Can be re-sized, "maximized" and "un-maximized" and appears to be normal.

Need to add that PC was rebooted multiple times, and error occurred each time Firefox was started up, after the reboot.
