Hi,

I,ve found that the Show-button of "C Block Comment Prefix" in *Customize Group: C* results in a non-closeable Hide-button.

(I represent buttons below with [])

Walkthrough to error:
M-x customize
Programming group: [Go to Group]
Languages group: [Go to Group]
C group: [Go to Group]

Before pressing Show:
C Block Comment Prefix: [Show]
   State: hidden, invoke "Show" in the previous line to show.
Specifies the line prefix of continued C-style block comments. More

After pressing Show:
<C Block Comment Prefix: [Hide]<
(*) Use style settings
<( ) <Override style settings: >>>>
