[OS X TeX] TeXShop crashing on window close

[David Craig]

I am using TeXShop 3.26 under Mavericks.    I am getting regular TeXShop crashes when I close pdf preview windows, either by clicking the close box, or cmd-W.  (A recent user posted "After closing the what's new file a blank PDF window has appeared, and then TeXShop has crashed.”   I see something similar: a gray, empty pdf window, before the crash.)

FWIW, my workflow is that I edit using Alpha, then typeset with TeXShop.  I have “Configure for External Editor” ticked and “Open Empty Document” (on startup) unticked.

An urelated issue: when I send a document to TeXShop from Alpha, usually the document/preview opens, but TeXShop does NOT typeset it right away until I hit cmd-T.   In the past (under Snow Leopard, that is, from which I migrated), TeXShop would typeset the document sent from Alpha right away.  Is there any way to return to the older behavior?
