It might be just me that gets this as I haven't seen anyone else comment about it, but who knows ...

When I am studying and I select a pop-up option, either details about the word / character or to add a new mnemonic, sometimes that pop-up won't appear. The top area of the pop-up appears, with the red cross showing, but the contents won't show. If this happens then none of the pop-ups for that word will work until I move on to the next word.

There doesn't seem to be a pattern for this, I know a pop-up has worked for a word, but next time I try, it might not.

I am using Chrome 9 (it claims to be up-to-date) on Windows 7.

Does anyone else have this issue or see any patterns that have caused this that could make locating the issue easier?

I've had the same problem intermittently for a couple of days. Chrome 9.0.597.86 on Windows XP.

Can you check your Chrome JavaScript console next time this happens to see if there are any errors (besides missing sounds), or even check its resource loading console to see if the HTTP request for loading the popup did something weird like never completing or loading an error? (It's Ctrl+Shift+J to get the JS popup, and if you don't know how to interpret the resource loading data, that's fine.)

I think I checked at the time and didn't see anything, but I'll keep an eye out for the next time.
