[Evolution] Evo calendar entries not updating

["carpetnailz researchintegration org" <carpetnailz researchintegration org>]

This seems to have just started happening: I go into a calendar entry
I've made and saved, add more text to the Summary, and save. But for
some reason Evo is not keeping what I've added to the summary. Sometimes
I can even see the addes stuff flash on the general calendar screen for
an instant and then it reverts to the earlier content. Sometimes it does
save on the second or third try.

I've made sure I tab out of the field, even tried by tabbing all the way
through the time settings, but it seems only to save the material some
of the time. 

Using Fedora 15 with Evo 3.03.

Any ideas?

Thanks
