Eclipse buttons, Google Chrome drop-downs and Ubuntu 9.10

I installed kubuntu 9.10, then installed freenx, then downloaded and installed Eclipse 3.5. Then while trying to add packages to Eclipse I noticed that clicking on buttons had no effect. I thought freenx wasn't sending my clicks to Eclipse.

And I also found that drop-down lists in Google Chrome were blank - if the drop-down had 10 items in it, then a drop-down with 10 blank lines appeared.

And then while installing the Android SDK I found a post linking to an explanation and workaround:

If you put

export GDK_NATIVE_WINDOWS=true

in your .bashrc your apps will behave correctly again. This saved me a ton of time troubleshooting!
