no answers to this??

hi there - I'm taking a Ruby class and have been using TM to code in and I'm having an issue with TM prompting me every 5-10min or so that there's 'another application' modifying my Ruby file and asking me if I want to revert or keep.

I've had this happen before when I've been simultaneously editing a file with both Coda or DW and TM, but in this case the file isn't open in any other app - except Ruby I suppose...

anyway - it's annoying and I'm wondering if it's some kind of auto-save built into Ruby and whether I can switch if off or whatever.

thanks, b

PS - love using TM for Ruby (as with everything else) - but just curious, the default Language for a .rb file seems to be Ruby on Rails rather than just plain Ruby - any reason for that? doesn't seem to matter much since the scope selector works just fine - I'm just curious.
