I'm guessing that this is a side-effect of FastScript's Smart Switching.
I've got some scripts for EagleFiler that I execute from FastScripts Lite. For certain actions, EagleFiler will ignore scripted commands if you're currently editing the same item in the UI. For most ways of triggering scripts, this is a non-issue, since they take the focus off these fields. However, since FastScripts doesn't take the focus, these fields don't get updated. I'm wondering if you've got any suggestions for working around this at a scripting level (activating Finder then re-activating EagleFiler would probably work, but seems like a rather big hammer).
I've already asked Michael about what was going on and he explained to me why EagleFiler operates this way. From his explanation, the effort needed to change this behavior would far outweigh the benefit to resolving this edge case, so I'm looking for ways to fix it at my end.
