    Posted: 12 October 2018 at 6:46am
We have an Openedge application currently using ActiveX 17.3 controls. I upgraded to 18.5 and now it crashes the entire application immediately on display of the task panel which is a docked pane using icons loaded by a separate ImageManager object using the Icons property. Without the icons, it works OK but we need the icons.

It doesn't make any difference what icons are loaded, using any icon at all will make it crash. I have tried swapping the order in which things are loaded and displayed but so far can't find a way of making it work. Has anybody got any ideas?

Here is the crash dump:-

I need to do some more investigation on this but this seems to be something to do with icon size. If I call SetIconSize with 32x32 and use an icon with a 32x32 image it seems to work, however if I set it to 16x16 which is what we use by default then it always crashes, even when using an icon which has a 16x16 image.

Hopefully this helps a bit in working out what has changed between versions.
