Context menu not appearing when too many items selected in find files results tab

1: XYplorer 28.30.2103 64bit
2: Windows 10
3: 100% Screen Scaling

There is an issue when selecting many items in the find files results tab. When selecting too many files with ctrl+A, the right click context menu no longer appears when right clicking them.

Demo video: https://mega.nz/file/5qgCGCyY#7jrCFR60i ... 0id-22lqaw
Sample file used in demo: https://mega.nz/file/Z7xHFB6B#6P1-kzPE5 ... j4KFUzS2V4

In the demo I have 2 top level folders: 01 Single Folder and 02 Folder of Folders. Both folders contain a total of 600 copies of the sample mp4 file. 01 Single Folder has 1 subfolder containing all 600 copies of the sample file. 02 Folder of Folders has 6 subfolders, each containing 100 copies of the sample file, for a total of 600. There are no issues with the context menu when all the files are in one subfolder. But in the case where they are spread out over 6 subfolders, the context menu no longer appears.

All testing was done on a local nvme drive. This seems to only happens on the 64bit version, I don't recall seeing it in the 32bit version.

The 32bit version cannot show the shell context menu for spread out files at all.

The 64bit case is on my list now.

Yes it can actually, tested in the 32bit version and the context menu comes up without issues on all 600 selected items that are spread out over 6 subfolders:

The 64 bit version can also handle some spread out files, here's the first 25 items selected, the context menu is appearing and by the path you can see the items are spread out:

That 32bit context menu is not a shell context menu but XY's own context menu.

Ah, didn't know there was a difference, sorry about that.
Anyway, that is the menu I'm looking for since it has the 'copy to other pane' option. Dragging tens of thousands of items from one pane to the other is beyond sluggish. Any reason why XY's menu can't open up on right clicking in 64bit like it does on 32bit?

Just tick this: Configuration | General | Menus, Mouse, Usability | Context Menus | Native context menu

Awesome, that makes the menu pop up for 64bit XY, thanks!
But just fyi, I don't have that option selected in the 32bit XY, so there's a bit of a difference in operation between the two program versions I suppose.

[admin]

Yes. The 32bit version does not even try to show the menu (because it knows it can't) and falls back right away to the native one. The 64-bit version tries and fails. I still have to investigate where and why it fails and make it fall back at that point as well.

[admin]

Over here it stops working with 409 or more items, what a curious and uninspiring number! Anyway, if possible at all, a fix will come later. For now there will be a fallback to the native context menu.
