pending mac carbon vm 3.8.15b3U

I've place a new VM (Squeak 3.8.15beta3U.app.zip) on my idisk and ftp  
site via

http://www.smalltalkconsulting.com/squeak.html

There are two bug fixes, one being how the VM interacted with a  
scroll wheel mouse where we would forget the state of the buttons on  
the scroll wheel move, that would cause unintended mouse up actions.

The other big change is that we now change the cursor back to a  
normal cursor when the cursor focus leaves the squeak window, and back
again when the cursor re-enters the squeak window. The behaviour I'm  
told is similar to what Windows users see.


3.8.15b3
                        sqMacUnixFileInterface.c
                                If you passed in an bad file path, say with incorrect encoding,  
then in convertChars
                                we would try to convert to UTF8, that would fail, but no check so  
code to do the
                                normalization would crash the VM

                        Cursor support change for Impara. Need the ability to change the  
cursor back to normal cursor
                        when we exit the window, or the application. Then when we re-enter  
the application or window
                        it should flip back to the cursor that was being used by Squeak  
when we exited.

                        sqMacHostWindow.c
                               
                                Add CreateMouseTrackingRegion() logic, add call in closeWindow to  
ReleaseMouseTrackingRegion
                                In ioSizeOfWindowSetxy call back to reset tracking region size.
                       
                        sqMacHostWindow.h
                                Add windowTrackingRef to window descriptor block

                        sqMacMain.c
                                Version number, and uuid change

                        sqMacUIEventsUniversal.c
                                When we setup events for window call logic to start mouse region  
tracking
                                Add mouse enter/leave logic
                                On application activate/deactivate need to set squeak cursor or  
initcursor
                                Add kEventWindowResizeCompleted to trigger rebuild of mouse  
tracking region
                                Add kEventMouseEntered and kEventMouseExited to handle cursor change
               

                                BUG FIX, deal with mouse move and button state, if you had an  
apple super mouse
                                you would have noticed if the mouse button was down, and you  
moved the scroll wheel
                                it would think the mouse when up, because we forgot to return  
cached mouse button state. Oops.
                                BUG was introduced in 3.8.12.b7

                        SqMacWindowUniversal.c
                                Add logic to remember cursor on cursor change and set flag if  
squeak had change cursor.

I noticed that in many situations where squeak was freezing using later
linux vms, if I managed to recover it it would be in the middle of
dragging a window which I hadnt persinally invoked.

could this be related?

No different code base, that would be X11 related.

I have noticed in some testing I was doing the other week  that  
squeak seemed sluggish to respond to UI events. The current model is  
single threaded on the UI thread, and
I was thinking that perhaps squeak is sleeping too long (an error?)  
and thus delaying the servicing of the event by os-x.  Likely I need  
to check this.
