formatting dumped when creating / updating post

To see the issue, view this post:

I align he photos on the left, below each other. Every time I get the photos lined up, even using manual HTML hand coding, WordPress dumps the formatting when I update post and I end up with what is viewed above. When I re-edit the post, any formatting / tags I inserted are gone. WHY?! I copy / pasted the code below, hopefully it is viewable here.

*NOTE* Obviously this post is screwed up. WordPress keeps dumping my formatting. Attempting to clean it up.

Here are some screen shots of PSM in 1024 x 768 screen resolution. My 22″ monitor is normally set at 1680 x 1050. Hopefully the photos will look ok on most computers. In pic one, note the custom memo column with reference info I entered for personal use.

I know I could have put them in a “photo gallery”, but it was a hassle attempting to add descriptions.

Note “account tabs” at bottom of screen. Also note “folders” on left of main screen.

Note names and memo column. The photo on the right shows ETFs sorted alphabetically by ticker symbol when I clicked on the ticker column. Can sort by any column.

In the right photo, look at the top stock, and note the % gain as of 01/24/09. Unfortunately this gain did not hold.
