what EXACTLY influences gwt designer preview??

[Elhanan]

i have 2 indigo's , the first at my home running on windows 7 64 bit, freshly installed , and another and my xp machine at work.. 

however the designer on the xp machine doesn't work well, for example if i try to add RootLayoutPanel to the entry point class on the xp machine it appears a mini dot (size 0,0 as default)  while on the windows 7 it appears ok (size 450,300 as default) 

further more, trying to resize stuff on the xp machine behaves incorrectly, so much so i begun to think i misunderstood the LayoutPanel system, i even attempted to use the exact same project, but still on the xp machine it behaves abnormally. 

on the xp machine i have IE 6 btw...

Ie6 is your problem. Upgrade to ie8 and your problems go away.

GWT Designer uses WebKit for rendering under Windows 7. Under XP, it has to use IE. That means any widgets/layouts will only be displayed as well as IE can render them. RootLayoutPanel requires strict mode which works much better in modern browsers. IE6 is the cause of what you are seeing. Update to IE8 (or Windows 7), and it should work much better.
