Steps to reproduce:

Inherit from button.
Add button to project's form.
Run project.
Make button Default.
Press and Hold SpaceBar (so button is pressed)
Move Mouse.
Release SpaceBar.

The button now recieves the first MouseDown and MouseUp events even if the
cursor is not over the button.

Has anyone else seen this? I couldn't find it documented.

What's more:
Inherit from ButtonBase and the Button will not repaint after a click by
mouse. It stays Pushed until it loses focus.

For anyone who's interested, both bugs are related.
The actual Bug is the ButtonBase one which Button then Inherits.
Simple Solution is to Override the OnClick and OnDoubleClick events and add:

MyBase.OnClick(e)
MyBase.OnLostFocus(EventArgs.Empty)

Nice one Mick. Cheers for sharing with the group. I wish more people done
this more often.

If you ever feel like solving the other 101 bugs in dotnet and Visual
Studio, feel free to share them too

And I thought no one was listening.

Are there only 101? :-)

I just thought I'd sort out the "No Icon in a FlatStyle.System Button" bug.
I thought it was going to be easy and to a certain extent it was, but I was
banging my head trying to figure out what I had done wrong to cause the
Paint errors I was seeing, and as it turns out it wasn't me, it was the
Tools I was using (does that make me a bad workman?).
I think I've finished it now, at least I can't think of any other things a
user might do to misuse a button.
Time to look over the code and see what improvements I can make.
