The demo program has this setting:
IEFolderMView.FolderInteract := [ieboOpenFoldersOnDblClick, ieboLaunchImagesOnDblClick, ieboLaunchFilesOnDblClick, ieboEnableFolderShortcuts,
ieboEnableFileShortcuts, ieboClickToSortColumns];
When I run the demo program side-by-side with Windows File Explorer (WFE) and try to use the hotkeys, Ctrl+C/V/X to copy/move files between the two programs, I run into some problems. I sometimes fail to press the keys carefully enough, so I miss even with File Explorer. I have tested with my ThinkPad keyboard and Kenesis Gaming keyboard to try to eliminate keyboard errors. And I habitually use the hotkeys even when I am testing the menu options. That makes it hard to get consistent operation. But I think I've got it down to this:
Ctrl+X frequently fails to enable the Paste icon in the demo. When this happens, WFE also fails to paste.
The Cut icon usually enables the Paste icon in the demo. And WFE paste works.
Ctrl+X frequently fails to enable the Paste icon in the demo. When I select a different folder in the demo, the Paste icon is activated and Ctrl+V succeeds. But the display is not updated. I am cutting a file at the top of the list so it should paste, then sort to the top.)
If I use the Cut icon, the Paste icon is enabled. I change to the target folder and Ctrl+V fails, but Paste icon succeeds.
Notice my use of the word "frequently". Just to be obstinate, sometimes it works as expected! I haven't pinned down any consistent situation though.
I get similar behavior from Ctrl+C but I think you've already fixed that.
I am using the demo as its own .exe, not from the IDE.
