launch c::b under ubuntu(kylin ver 1604 ), try open the dialogs of "Settings/Editor", "Setting/Env.."
. the dialog randomize been "frozen" (the dialog is blank).
This bug is with these version
1) c::b version: build with svn nightly build
2) apt-get install from ubuntu.
3) apt-get install from the un-offical ..
------
and after "frozen", I have to kill the c::b process
Have you applied all the updates? It could be some driver issue (it is not the first time it has happened).
Or the patches Ubuntu applied to move the menu to the top... What happens when you disable that feature?
