Hi John,
build 1.34 is ready for testing. You should have received an email notification.
In this build we are hoping to achieve a good level of stability so please keep an eye out for any unexpected crashes, etc.
Also, in the new GUI you need to 'unlock' by pressing the 'unlock' button in the top-right hand corner for a few seconds to show the close buttons and the tabs (to rearrange the windows). The control windows will autolock by themselves. This reduces clutter on the screen by hiding the close buttons/tabs most of the time.
Let us know how it goes! Thnx.
