In Precise, weka (java) windows always open in a different workspace
Weka is a machine learning package in Ubuntu, written in java.
As described by @ubershmekel at:
12.04 - Weka windows always open in a different workspaces - Ask Ubuntu
"On 12.04 every time I open weka it starts in the second workspace. If I move it to workspace #1, all the new windows it opens are in workspace #2. If I try and work in the 2nd workspace, new windows are opened in the 1st. There's no way for me to avoid being hassled by weka."
I have the same problem, so this should be easy to confirm, and I'm guessing it is unity-related.
$ weka -m 512m

I think we can safely ignore these error messages since database access is not necessary.
I expect to see a GUI window pop up. Sometimes I see one briefly flicker in and out of view, but mostly it just seems to hang. But if I then use the Unity Workplace Switcher to look around, I'll see that the window opened up elsewhere, e.g. workspace 2. Then if I go there and open a further window up e.g. by clicking on "Explorer", nothing seems to happen, but in fact it opens that up, but yet again in a different workspace, e.g. back in workspace 1. Very frustrating.
I'm using icedtea 6 on a 64-bit machine.
