Since the update, I am experiencing a slow response to ctrl-clicking on an object. So I'll ctrl-click (or right click) an object, or message, or array to look at properties or help and the menu is very slow to pop up, then it doesn't really respond when I hover over the options (properties, open, help). When I click on one of the options it kind of freezes before finally opening the help or properties.

tl;dr - Is anyone else experiencing very slow response when ctrl-clicking on help/properties of an object or array?

Yeah I have the same problem on the Mac with version 0.43.4! Also when it's in the frozzen state it starts using 100% of the cpu

Yes, same problem here (mac os 10.6.8 - pd 0.43.4).

Also, I had an issue with subpatches that include abstractions which are graphed on parent: there were error messages about invalid command name, etc. It's something with tcl I don't know anything about.
However, what solved the problem was to disable graph on parent for the abstraction. It's not a problem in this case, but strange anyhow. Any similar experiences?
