When accessing the back office from a Windows 98SE PC in Firefox to enter a new post, the "write" text box is shifted over more than half the width of the window, with nothing but blank space on the left. (It is still within the "write" tab, and clicking on the other tabs displays their contents normally.) This is the same for "simple" and "expert" sub-tabs. Selecting view>page style>no style and then going back to view>page style>desert corrects the problem, but is not obvious for my other novice users.
Any suggestions for correcting this issue?
