IB TWS Slow Reaction SOLUTION

[H2O]

I saw some people were having problems with TWS when using a multiple monitor system. TWS was slow to react until you move TWS to another screen and back.

I read this post on another threath and this solved the problem.

The Following is a letter I received from IB Tech support solving this problem for me, maybe it will help you. I disable Java and now things work fine. I really wish IB would ditch this Java stuff and Use something else. Java Programs always slow my machine down, I really dislike them.

" It sounds like a conflict between Java and your video drivers. There are a few things you can try.

Get the most recent drivers for your video card
Upgrade your version of Java. (the most recent is 1.4.1)
**if you upgrade Java, be sure to uninstall old versions first & reboot If you are using the standalone version you can change the shortcut to disable DirectX
**to do this follow these steps

To do this, right click on the Trader Workstation 4.0 icon and choose "Properties". Then click on the "Shortcut" tab. In the "Target" field add the following line before the -jar

-Dsun.java2d.noddraw=true

So that the entire line looks something like this...
(assuming that you have java 1.4.1_01 installed)

C:\Program Files\Java\j2re1.4.1_01\bin\javaw.exe -Dsun.java2d.noddraw=true -jar C:\JTS\jts.jar C:\JTS

-end of e-mail-

I don't know what this line (-Dsun.java2d.noddraw=true) does, is there some JAVA expert out here who does ?

I believe it disables Direct Draw. I had to do this on my PC. Before doing this, my computer would automatically restart everytime I logged out of TWS.
