Thanks for reporting. Both issues should be fixed in the latest 
development version.
Regarding the second point: for reference, the process of determining 
which source file to use/open is currently as follows:
If a suitable source file is already open, use that
If synctex is available, use that to determine a suitable source file 
(by simulating a ctrl+click in the top left corner of the first page)
If the previous steps fail, try to find a file with the same name as the 
pdf but the extension .tex (I know that this is flakey; people might 
prefer .ltx or something else; they might override the \jobname or do 
other things that break the underlying assumptions; but for 99% of the 
use cases, it should work just fine, I hope)
If all else fails, disable the typeset button (rather than have it 
enabled but effectively do nothing)

HTH,
Stefan
