Hi,

Since upgrading from Jessie to Stretch, a bell in an xterm (commonly generated
by tab completion or pressing ^G) always opens "Warning - KDE Accessibility
Tool", which asks 'Do you really want to activate "Sticky keys" and "Mouse
Keys"?'

Selecting "Deactivate All AccessX Features & Gestures" and choosing "No" does
not stop the dialog appearing again.

In "Accessibility - System Settings", "Activation Gestures" tab, "Use gestures
for activating sticky keys and slow keys" is turned off.

This is also mentioned at

Thanks,

Roger
