Anyone else just have TWS disappear? I don't remember this
happening before....
They won't let me re-login either...
Had this same problem in the summer (re-login wasn't a problem though) for some weeks. I upgraded SUN Java JRE to 1.4.0_02 (and maybe TWS too) and the problem disappeared. I even forgot that I ever had this problem until your post.
Open the Command Prompt window and type in
java -version and hit return. What version of java does it say you are running?
An alternative is to go to the following link and it will automatically tell you what version of the Java virtual machine you are running:

It seems you do have Sun Java installed. I was wondering if you were just using the MS Java virtual machine which would be way out of date if you were.
The term plug-in refers to the browser java and I'd like to know what version of standalone java you have. I'm guessing your standalone version is the same as the plug in. Assuming you also have 1.4.0 standalone java installed, you need to upgrade to the latest non-beta version from the Sun website.
The 1.4.0 version had problems and many bug fixes have been released since. IB may not even be supporting that early a version of java.
The download link to the latest Sun java version is

Once you install the new java, right click on the TWS icon, go to Properties and update the startup string to relfect the location and name of the new JRE (Java runtime environment).
Is this what you wanted to be put in?
C:\Program Files\Java\j2re1.4.1_01\bin\javaw.exe -Dsun.java2d.noddraw=true -jar C:\JTS\jts.jar C:\JTS
Right now this is what is in TWS:
C:\Program Files\Java\j2re1.4.1_02\bin\javaw.exe" -jar C:\Jts\jts.jar C:\Jts
When i added in what you said to, it brought up a window
saying something like it wouldn't start TWS because of some
reason I don't remember!

that's a concern I have with the whole idea of a java-based trade execution platform, as java applications are sometimes unstable and dependent on specific pc configurations ...
I have to spend a lot of time helping traders configure java for things like chat room access so it works properly for them ...
java: when it works correctly, it's great, but sometimes there's installation and pc-specific issues to resolve first.. eg which version of java to install, how to make sure it's the only version installed etc ...
I hope sun continues to evolve java into a more universally "works right the first time every time" background language for apps that need it, as it's an excellent tool when it works ..

Don't just copy the whole string. I hope you saved the original string. Simply take the -Dsun.java2d.noddraw=true snippet and insert it in YOUR startup string. The string I posted was an example. Your string will be different depending on the folder in which your java was installed and what you called it.Quote from version77:
