I'm not using anything unusual, apart from IntelliJ IDEA and JIRAClient - both are Java applications and I'm using a stock OpenJDK JVM for them. No other closed-source software. I don't understand what triggers it, but it happens pretty regularly.
>as for changing icons. if you right click on the shortcut and go to 'edit launcher', in the window that comes up, click on the icon and it will pop up a new window to let you select a different option (I assume that by shortcut you are taking about an icon on the taskbar here)
Well, there's no such option for me. I can change icon for the file type, but of course it changes it for _all_ bash scripts.
>with your task bar positioning, my guess is that somehow you are not ever getting the change saved after you reposition it. next time you reboot your system, try logging in, making your changes, and then log out and log back in.
Does not work and it would still be a bug in any case.
