Hi John,

I do see that macro in Genera CLIM spec v2.0 for `clim:pointer-cursor`. Whether this is a regression or not is before my time working with McCLIM, but it does seem like it should be... I was able to replicate that it isn't working for me either.

After looking a little in the internals, it looks like McCLIM won't change the cursor of a sheet that has a direct mirror. It looks like that prerequisite was introduced 8 years ago in commit d95dfd91517106cc6a84774434c69c1386453abc. I experimented a little in the clim-listener application and this snippet did work (as proof of concept):

```

CLIM-USER> (setf (sheet-pointer-cursor (pointer-sheet (port-pointer (port *application-frame*)))) :busy)

```

I'll see if anyone knows the history on IRC and whether it should have a fix.

Thanks,

Charlie

Hi;

Sorry if this is either a dumb question or Pilot Error, but I am having trouble showing the user a "busy" cursor when a long-running command is invoked.
Current "master" codeberg McCLIM
Fedora Core 41
xorg-x11-server-Xwayland-24.1.8-1.fc41.x86_64
SBCL vintage 2.1.1 (homebuilt)
I *THINK* I used to be able to do this years ago running under X11 (vs Wayland).

Please find attached a hopefully short program which either shows the problem, or shows my ignorance.

Thanks in advance for any help.
