I've push a mac vm 3.5.1b4 into the update stream which should appear on the servers in a day or two. Early adopters can email for a copy.

3.5.1b4 Please note the major changes to network code in 3.5.1b2

a)Added options SqueakWindowType & SqueakWIndowAttributes to info.plist. The SqueakWindowType of 6 is the standard document window, a type of 8 is the floating utility window. The attributes control with window attributes and behavior according to http://developer.apple.com/techpubs/macosx/Carbon/ HumanInterfaceToolbox/WindowManager/Window_Manager/wind_mgr_ref/ constant_2.html#//apple_ref/c/tdef/WindowAttributes & http://developer.apple.com/techpubs/macosx/Carbon/ HumanInterfaceToolbox/WindowManager/Window_Manager/wind_mgr_ref/ constant_1.html#//apple_ref/doc/c_ref/WindowClass b) Sockets are not valid if the network is not initialized. c) The os-9 vm can return the open file error in the vm attribute data 1202 d) MyWindowEventMouseHandler was leaking region handles. e) Support for primitiveClosureValue, primitiveClosureValueWithArgs, primitiveExecuteMethod f) when rootTableCount goes > 2400 then allocationCount gets allocationsBetweenGCs + 1 g) BitBlt Alpha Blending has changed h) Added primitiveWrite24BmpLine i) The guard if statement for primitiveSerialPortRead was flawed, noted the buffer overflow, but then proceeded, versus returning.

3.5.1b3 a) Fix, Stephane Ducasse ducasse@iam.unibe.ch pointed out that using a virtual desktop we had a crash in ioSetFullScreen. This was due to a pthread race condition between the UI thread and interp.c. Fixed by using UI callback to handle fullscreen window/move/resize.

3.5.1b2 a) Switch to aio.h logic and unix socket logic! This is a MAJOR change!!!!

b) Call aioPoll (select()) to cause process wait versus old pthread logic. This follows in the footsteps of the unix port. You should verify that cpu time when squeak is idle is not affected in a dreadful manner. c) Fix, if you call does this directory exists on a file now you will get an error which will signal that the directory does not exist. This ensures the FileDirectory test suite works. d) Fix, if you quit the browser plugin, check the status of the pthread_cancel before attempting the pthread_join
