Error box closing

Hello, error boxes don’t close properly on
RISC OS 5.27 (19 Mar 2020)
Window Manager 5.71 (30 Jan 2020)

If I make one appear (e.g. click on empty floppy drive), and dismiss it by pressing return (important!), rather than closing the error box, it closes whatever window happens to be under the mouse pointer at that time (which is why you have to press return for this to work).

After this, the error box remains on the screen but you can drag it around. If you drag it to the edge of the screen, the whole desktop freezes.

I discovered this while I was investigating another issue (Crash caused when trying to use ShareFS logon submenu with empty Name field – see also https://www.riscosopen.org/forum/forums/11/topics/15093), but I don’t know yet if they are related.

Thanks

RO5.27 (07 Mar 2020) & WM 5.71 behave as expected here.

It’s an RPCEmu problem: when Follow Host Mouse is turned off, the pointer isn’t constrained inside the error box.

I guess the Wimp must be using GetPointerInfo to get the window handle of the error box on the assumption that the pointer will always be inside the error box.
