We still have issues displaying the systray-icon of
in explorer systray. see react-r70327-systray.webm
It does so by changing implementation of ImageList_ReplaceIcon()
for index > maxIndex to show the same behavior as for index == -1
(add the image)
I guess comctl32 is the right place to fix it, but I can not verify easily with XPs comctl32 in ros, as no icons are drawn then at all.
I have been running the hackfix for several months without an issue. We should work on a proper solution for that issue.
