Studio theme - Widget area changes not being read by theme.

Hello,
I have been using the Studio theme successfully for about 8 months now and this is the first time that this has happened.
When I make changes to the content of a TEXT widget it has stopped reading any changes, including the deletion of the text widget altogether. It's not the cache or cookies ( although I did clear them all out on both Chrome and Firefox of the computer I'm using), because if I use a browser on a PC that has never been to the site it is still pulling up an earlier version of the widget.
background:
I was making changes to twitter stream feed script in a widget (that has been working great for a few months),but after a handful of changes it just stopped updating or reading the changes I was making. I even deleted the text module that contained the content I was editing and it doesn't register the changes.

Its like its stuck.
Any thoughts?
thanks
