Auto-Stretch and the BACK - FORWARD buttons -- HELP!

I've also posted this question in a HTML news group -- but no response has come... so I'm hoping some here might have experienced this before and can be of assistance. --- My tables autostretch *with* the browser... when I click my submit button on (say) Page1/Form1 -- everything auto-stretches just fine on the next Page/Form (ie. my tables -- which are colored -- are flush with the right and left sides of my browser... which is IE 5.5) However, when I press my browsers BACK button, then FORWARD button the page is no longer *flush* on the right hand side (and I haven't resized the browser) -- I have to do a RELOAD / REFRESH to pull the page back in, then it's flush again -- this is highly annoying and I know I've seen other sites where this doesn't occur. It gets "off" about a 1/2" on the right side -- then all pages that follow are all off, unless I (of course) refresh. My BODY tag reads as follows: <body width="800" bgcolor="#FFFFFF" text="#000000" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0"> Any tips on how I can correct this? It needs to be flush irregardless if the user presses the BACK button or not. Thanks. Jason jason@thinkingman.org
