I am afraid I haven't got steps to reproduce the symptom yet as it occurs periodically in different situations. ==== What is the expected result? Further editing is possible. ==== What happens instead? I have noticed two situations in which it occurred, the bug information below is from 2: 1. When adding a new relation the exception occurred while trying to edit it to add a way. An exception dialog appeared with option to report or ignore. After opening the ticket reporter closing the dialog returned back to the editor which seemed still functional except the exception reoccuring repeatedly when trying to edit the relation. I was able to continue editing and upload with the exception of keyboard shortcuts being ignored. The bug report from this incident was never reported but it was positively the same ""Window must not be zero"" exception. 2. When trying to add tags to a newly added way by pressing alt-a the same dialog appeared resulting in this bug report. In the same way I could continue editing but without keyboard shortcuts being available. This time the exception reoccurred a couple of times but after that I could continue tagging. It seemed like the window did not have proper focus as the menu bar didn't become highlighted as it should. Nevertheless pointer movements, mouse clicks and keyboard input in upload/tagging were received by the application. Suddenly though it froze and after letting it hang a while it reported excessive memory use (around 1.8GiB) when trying to close the window. At this point I made the following dump of the process: {{{ $ ps -p 26691 -v PID TTY STAT TIME MAJFL TRS DRS RSS %MEM COMMAND 26691 ?
