Default cursor for control doesn't work

[Ocye]

I have a panel with a small side area of 3px where the cursor is changed to crSizeNW/SW etc. (it's a resizeable panel). On the panel is a control, ie. listbox or glcontext. The embedded control has crDefault property. When I move the cursor with the right speed it isn't changed to default pointer sometimes. I tried with OnMouseLeave code for the panel but that didn't help. When I replace the cursor of the embedded control with something else like crCross it runs perfectly. What can I do?
The problem does not occur under Windows.

Qt or gtk2 ?

Gtk2. I'll check Qt this evening.

No problem with Qt. Openglcontext not tested since it isn't supported.

PS: I put some controls together and it is an issue with Qt too. To reproduce place a panel on a form and change cursor to crHourGlass. Add a listview to the panel and make it alClient. The cursor will change when moving over the bevel but stays an hourglass at the listview which cursor property is crDefault.

PPS: Arch Linux, KDE 4.8.2

That's because qt changes cursor for parent (TPanel) and then to all of it's children all the time.

Is it good to link cursor to parent? I don't think so but I should blame Qt for that. Or XOrg?

The question remains: How do I use the proper default cursor for embedded controls?
