[TxMt] TM2 very slow durning edits

Dear all,

I'm just playing with the latex bundle and TM2. Every time I do anything like edit text or save TM2 freezes and takes up one core on my machine. I this due to 'attr.save-on-deactivate' ? my .tm_properties file looks as follows:

####### PATH = "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/texbin:/usr/bin/local:/Library/Frameworks/GTK+.framework/Resources/bin"

[ *.{R, c, cpp, m, pl, rb, html, xml}] scopeAttributes = 'attr.save-on-deactivate' ######

Also quick 2nd question how do I get the compiled pdf to appear in a separate window like TM1 instead of at the bottom of the window?

Cheers,

Paul
