Comment 20 for bug 1206880

OK, tried version http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-rc7-vivid/, the problem persists, but now event the "Always trust content from this publisher" checkbox is not clickable after trying to use the touchscreen (not even with a mouse). I can only close the JAVA window by clicking on the X icon at the upper right corner of the window - even with the touchscreen.

Edit: Hm, strange. After playing with it for a while, I can sometimes click on the checkbox (but not on the butons).

Anyway, after Xorg restart, mouse works.
