BoundsChecker found a memory leak in InitDialog because  the CImageList pointer is allocated on the heap with
"new" but never deleted.  
To solve this leak, I made pImageList a private variable instead of a pointer.

CImageList m_ImageList; //add this to the header file

You have to change the references to pImageList from pointers (pImageList->Create, etc.) to
non-pointers (m_ImageList.Create, etc.).
When this is done the memory leak goes away.



When you change drives, and if the current directory on the new drive happens to be root you get an
error(compiled under VC++ 4.2)because in the Add dirs to tree routine

void CDirectoryTree::AddDirsToTree(CString szStart, HTREEITEM htParent)
{
	szStartDir.Format("%s\\*.*", szStart);

szStart is something like "c:\" so it already has the slash unlike
"d:\mydir" that does not have the slash. So you have to distinguish based on the current
directory name. A simpe way is as following


	int len = strlen(szStart) - 1;
	if(szStart[len] != '\\')
		szStartDir.Format("%s\\*.*", szStart);
	else
		szStartDir.Format("%s*.*", szStart);

aLSO vc++ 4.2 complains about memory leak that I did not have time to look into.
