I am using the popular browser Firefox, version 1.5.0.7 running on Suse Linux 10.0.

I went to http://cutesoft.net/example/general.aspx, pressed the HTML button and pasted in my original code, then I pressed Preview, then pressed HTML.  At this point the dashed code appeared and I saved a copy.

Next I pressed 'Normal' then pressed HTML.  At this point the code I call 'tbody code' appeared.  It does not have dashed lines but has added 4 <tbody> statements.

Apparantly there are two versions of modified code.  Wich one is displayed in HTML mode depends on if you have most recently used 'Preview' or 'Normal' button.

My original code:

The dashed code:

The tbody code:
