LiveCharts Exception

[rduclos]

Recently having trouble getting LiveCharts 3.1 up and running quickly: have been getting a "General Exception - java.util.ConcurrentModificationException" after log-in (I have the details recorded as an image).

When this occurs the LC chart display is frozen and I have to kill Firefox entirely to restore functionality, which affects other web sites I am using. I get LC running properly after several attempts.

again today

This happened to me again today, though not Friday or Tuesday:

livecharts

Are you running the latest version of Firefox and the latest version of Java?

[rduclos]

(two months later
This is still happening to me most mornings when starting LiveCharts for the day. Usually takes two or three attempts before I get the applet running, then it runs fine all day.

All my software is up-to-date, Java, Firefox and Windows, though the Windows is XP SP3, so I suppose that is not the latest, stictly speaking.
(I dislike Windows 7).

We are looking into this issue, I will post once we have some more information.

Something has changed

Three days in a row it has started on first attempt. This is the first week in months I have had no problem starting up (usually took three attempts before).

LiveCharts

Good to hear that it is working a bit better for you currently. We are constantly working to improve the LiveCharts product. Let me know if there's anything I can assist with.
