The vdraws sample does have the same problem, will look into it. Its a bug.

So if you set breakpoints in sttool.cpp on every sm_toolPoped interceptions,
and next run vdraws sample, it does not stop?
Here it does, so i think you never Pop any tool??
In tools.cpp put on a2dComEvent event( GetFirstTool(), poped,
&a2dBaseTool::sm_toolPoped ) a breakpoint.
Be aware that pushing a tool does not mean automatically popping the last tool
first. Often the tool is pushed leaving
other tools intact on the stack.

You can define your own top tools and set its cursors, or not?
void SetCursorType(const wxCursor& cursor) { m_toolcursor = cursor; }
void SetBusyCursorType(const wxCursor& cursor) { m_toolBusyCursor =
cursor; }
