right click window in word 2010(technical preview)

[hemn]

Hi,
I have recently updated my Office 2007 to 2010(technical preview) and eagerly opened the Word to type a letter, after making the first misspelling word I have right clicked on it to choose from suggestions, but the window is not stable to choose from!! only shows for a very short time and disappears. Does anybody knows the reason? or it's because of being the beta version( I don't think so)?

Please comment your ideas,
