Problem when accidentally trying to close wiki in Tiddly Desktop with unsaved changes

I’ve been using Tiddly Desktop for some time and have noticed a consistent behaviour when accidentally trying to close a wiki when there are unsaved changes.

The dialog comes up ‘Are you sure you want to close this wiki?’ I don’t, so click cancel but then the box keeps reappearing and it’s not possible to save the wiki by the red button until the box disappears. The number of clicks needed to clear the dialog varies, but this morning it was over 40.

Wonder if anyone else had experienced this?

Yes, this is an issue - but I know no solution except killing the task…
