Which led me to download an archived version of the "Microsoft Performance HUD tool" -> http://web.archive.org/web/202207191116 ... ?id=100813
Which in turn reported the following GDI leaks in my exe in the screenshot below.
As you can see, the "Description" column shows me which items I need to re-check for leaks. I'm VERY hopeful now!
This is such a fantastic tool to have! Don't know why Microsoft discontinued it, but at least it's been archived for download.
BTW, this app attaches a little window to your own app's window so you can see its CPU %, memory, GDI count, etc. No need for Task Manager!
Hope this post helps someone else in future.
