Created an attachment (id=328958)
 --> (http://bugzilla.novell.com/attachment.cgi?id=328958)
test.cs

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1;
Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729;
NET4.0C; .NET4.0E)

When the mouse is captured (Control.Capture = true) the mouse location in
MouseMove event (e.Location) is invalid if the mouse pointer leaves the
control.
In the attached testcase, when clicking into the white panel and dragging the
mouse outside the panel, the location jumps to the location of the form.
Vice versa when clicking onto the form and dragging over the panel, the
location (which is shown in the title bar) is also invalid.
This behavior makes it very hard to drag controls programmatically.

Reproducible: Always

Steps to Reproduce:
1.compile and run attached testcase
2.click onto the white panel
3.mouve the mouse pointer (pressed) outside the panel and view title bar

Actual Results:  
Location jumps

Expected Results:  
When the mouse is captured, the Location should always be relative to the
Control

Seems to be only a OSX bug.
