Q: Ical " Server responded with an error" and the string so long cant see bottom of the window to delete. and its locked up Ical

In Ical " Server responded with an error" and the string so long cant see bottom of the window to delete. and its locked up Ical.

I had originally cut and pasted my airline travel confirmation and guess it was TOO long and now I cannot get to bottom of the window to delete / cancel etc.

The Ical is locked up and just makes BEEPS when I try to edit.

Help!

Thanks in advance..
