I'm not sure you can change that.

However try:
File -> Options -> Object Designers

That is the only font settings for the Access Settings  (other than the Zoom Box ) that I know of for the program itself.

Thanks Scott, The way you metioned only changes the default desgin of the pic.

I was afraid of that since it specifically mentioned Query Designer,

I that case - unless it is controlled by a Windows Setting - I don't think it can be adjusted.

so as your experiences of access, you think the problem maybe by windows setting? what do you mean of " i don't think it can be adjusted", the windows can't solve the problem, either? this small problem affect my working feeling, let me feel not good.

I'm saying - That is not a setting in Access that you have control over or one that can be changed.  It just is what it is - I care how you feel but apparently Access doesn't.

With regard to Windows setting I know there are some screen settings that can be controlled but that will affect all programs.  I don't think that is what you are looking for.

i am wandering why your setting can be that font format.

I don't think you can change it in Access.

thank you for your reply, Dear Richard. i tried to change the access unit kingdom version from unit states, it works. even if it still can't be changed, but it changes another font format

i can't stand the origenal format

Sorry you don't like it.  Might want to take it up with Microsoft.  

Mean while it serves no purpose to keep posting about something we can't help you with and that we don't have control over.
You will just have to accept it and move forward.  I'm sure you have more important issues to work out.

Alexis,

After reviewing your screenshots, are you meaning the Office Theme?
File - Account - Office Theme

Dear Kevin, it's not office theme, but thanks. yeah, i have important issues to work out, Dear Scott, and i don't know whether you can control it or not, just only same design view with the video of Mr. Richard. but thanks for all. by the way, i really really can't stand the design view font format of our Chinese version, anyway, thanks for all
