VAX 1649, VS 2008 SP2, DX SDK installed.

When hovering the closing parenthesis in a _countof(xxx) statement, a huge tooltip is displayed with stuff from DirectX:

inline _D3DMATRIX operator * ...
inline _D3DVECTOR operator * ...
...
D3DX10INLINE ...
D3DX10INLINE ...
...


Crazy.

Do you get a sensible tooltip if you hover over the actual function name "_countof" or the parameter "xxx" ?

See above: "...hovering the CLOSING parenthesis"
Hovering other parts of the statement yields sensible tooltips.

This is why I asked. I would not expect hovering over the closing parenthesis to offer any form of tooltip at all. It is not a natural target for mouse hovering, since it is only a single character. Also it is common to get several closing brackets in a row.

Are you deliberately hovering the mouse over the closing bracket, expecting a sensible tooltip, or is the mouse just ending up here by accident?

I was bored and took an extra look at the provided VAX-tooltips. So I put the cursor there deliberately.

I didn't expect a tooltip, but got the strange tooltip described above... now what? :P

Feel happy since VA adds hours of entertainment to your working day. Just hover your mouse over random brackets and watch for unexpected tooltips

This is hardly a serious bug that we need to worry about, at most it is an interesting oddity.
