I started a thread on the RISC OS open Forum at https://www.riscosopen.org/forum/forums/5/topics/14945?page=1#posts-97826
for more details. To sum; On closing windows in NetSurf choices/configuration I’m seeing the error, ‘An unexpected error occurred: Illegal window handle’. It only happens on alternate config categories and on first look doesn’t appear to do harm. It’s on RISC OS 5.27 (19-12-19) ROM, NetSurf 3.10(DEV CI #4956). To summarise the thread, it's due to the latest version of RISC OS improved reporting of errors, showing this one up. It's been confirmed by others and is said to be related to changes in that ROM relating to clipboard caret/task fixes. NetSurf log extract; (9.520000) frontends/riscos/wimp_event.c:1654 ro_gui_wimp_event_get_window: Creating structure for window 0x20481e39 (10.850000) frontends/riscos/dialog.c:378 ro_gui_dialog_close: xwimp_set_caret_position: 0x288: Illegal window handle (10.850000) frontends/riscos/gui.c:2112 ro_warn_user: WimpError Illegal window handle (10.850000) frontends/riscos/wimp_event.c:1112 ro_gui_wimp_event_close_window: Close event received for window 0x20481e39 Anything else - best to follow the ROOL forum thread. I'm not qualified :-)
