In 188.8.131.52, I make a connection and open the SB to the Triggers tab. If I click on a trigger in the LHS, the source dutifully shows up on the RHS. If I change triggers twice on the LHS before the source shows on the RHS for the first trigger, no source shows up on the RHS for the second trigger either. I can’t replicate this on Procedures, though. The source comes back faster than triggers, but even though I think I’m clicking faster than the RHS refresh (thanks to daily gaming and copious amounts of caffeine), the source shows perfectly every time.
This is low priority, as one can switch triggers slowly on the LHS and recover easy enough, but thought I’d mention it here in case it could lead to other issues.
