Memory leaks and resource leaks?

I used boundchecker 6.5 to debug the any sample debug exe. such as GUI_VisualStudio7d.exe

The boundchecker reported some memory leaks such as
in CXTPPaintManager

CXTPPaintManager* CXTPPaintManager::CreateTheme(XTPPaintTheme paintTheme)
{
...
 if (paintTheme == xtpThemeOfficeXP) pInstance = new CXTPOfficeTheme();
...

it said the 'new' has memory leak...

and in some other file had same memory leak alarm....

Could anyone verify and explain it?

Yes Oleg,
I check it is a good trick to release the memory.
But I wonder why boundchecker report and visual studio not. Is it because the .dll is called?
