Embedded Forms - sometimes will not save updates

Embedded Forms - sometimes will not save updates

I have a series of embedded forms in a wordpress blog. We access the forms from multiple machines every day. Sometimes some computers will not save updates to some forms - we get the saving message that never goes away.

Its only some computers some of the time and it only effects a single form. The forms it effects are different every day. I have tried using a new browser, clearing all browser history and even restarting the computer - none solve the problem. 

Any thoughts on either how to fix it perminently or how to clear the error when it occurs.

Thanks
Kevin
