Hi, I told you that I'm now running a patch Emacs version which works arounf the non existing window and which reports the ID. Now I got three reports: drepper＠otr drepper$ Failed to find frame for window 4800177 Failed to find frame for window 4800177 Failed to find frame for window 480009b I don't know whether they appeared all at the same time. I only saw the messages suddenly. Anyhow here's the xwininfo output: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ xwininfo: Window id: 0x4800177 (has no name) Absolute upper-left X: 1000 Absolute upper-left Y: 92 Relative upper-left X: 565 Relative upper-left Y: 67 Width: 15 Height: 243 Depth: 16 Visual Class: TrueColor Border width: 0 Class: InputOutput Colormap: 0x23 (installed) Bit Gravity State: NorthWestGravity Window Gravity State: NorthWestGravity Backing Store State: NotUseful Save Under State: no Map State: IsViewable Override Redirect State: no Corners: +1000+92 -9+92 -9-433 +1000-433 -geometry 15x243-9+92 xwininfo: Window id: 0x480009b (has no name) Absolute upper-left X: 1000 Absolute upper-left Y: 352 Relative upper-left X: 565 Relative upper-left Y: 327 Width: 15 Height: 245 Depth: 16 Visual Class: TrueColor Border width: 0 Class: InputOutput Colormap: 0x23 (installed) Bit Gravity State: NorthWestGravity Window Gravity State: NorthWestGravity Backing Store State: NotUseful Save Under State: no Map State: IsViewable Override Redirect State: no Corners: +1000+352 -9+352 -9-171 +1000-171 -geometry 15x245-9+352 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is on my laptop which has a 1024x768 display with 16 bits. The Emacs window is at the right side of the screen. Therefore I'd say these windows are indeed scrollbars. Now that the problems are simply ignored Emacs still runs nicely. If you have more to test just send it.
