...;s the nuisance part. The second problem is that the device may try to plot() into a non-existant window. Assume that the window was destroyed by some other part of the program. The device (at some point in the future) will receive a DestroyNotify event that handleEvent ignores. Blissfully! *No KillDevice is called* when the window is destroyed by something other than the WM_DELETE_WINDOW mechanism! This happens when you embed the X11 device into another window/application. For starters, the device no longer receives WM_DELETE_WINDOW client messages. But it does receive a DestroyNotify event when...

It does fix the crash, however, and should be along the right lines. The rationale is, that apparentl...
