I know I must have clicked on something by mistake, but I can't figure this out:

I've been working on the same .veg for about three weeks now - no problems, moving stuff all over, applying fades, transitions, color correct - whatever.

All of a sudden, I open up the same file, and I can NO LONGER apply transitons to events. Moreover, when i slide an event to overlap another (normally resulting in a simple cross fade) - it no longer even does that - it just slides "underneath" the other event and I get no transition whatsoever.

Bizarre - but hopefully something simple that you more experienced users might be able to help me out with.

Thanks in advance for your help
