Dear BCB list,

There is  confirmed bug in the TPaintBox component in C++Builder 3 and 5. A
description of the bug is shown below.  I have given up trying to get
Borland to fix this.  A work around has proven very difficult so now I am
trying to find a third party component to use as a replacement for
TPaintBox.  If you know of any vendor who has an TPaintBox component which I
can investigate please post a web address.

Thank You
Patrick Mikula.

Not difficult. Call GetCursorPos() to get the absolute cursor
position, then ScreenToClient() to translate it to the component's
co-ord system.

Sometime it may not be true. GetCursorPos() returns
current cursor position, but OnMouseDown event contains
coordinates when event/message was occured.

In theory that's true, but in practice you'd rarely notice it. Calling
GetMessagePos() in the handler instead would avoid that problem.
