kmail TAB wierdness

While writing my last note I ran across an oddity related to tabs. When I tab in to indent a sentence the cursor becomes offset by the spacing of the tab. For example here's an indented sentence. If I try to insert a word just before the word "sentence" (by clicking the mouse just in front of the letter s) the blinking curser shows up between the "i" and "n" of the word "indented" The inserted word will go where intended but the visual reference is disconcerting to sat the least. Has anyone else encountered this? Is it a bug or can I disable this peculiar "feature" (without switching to mutt or pine I mean ;-p) dh
