Addresses with line breaks in the message window are activated by clicking very far to the right of them. This is annoying to me because I often happen to open a compose window when I just want to activate the main window by clicking on free space in it. Solution: Only react to clicks when the mouse pointer is over the address (as it happens when the addresses are not split up by a line break).
Works fine for me. Please attach a message file which demonstrates the behaviour that you describe.
Unfortunately, this is not currently possible, sorry. I thought it would be doable by setting "wrap-mode" and "wrap-mode-set" attributes for the "hlink" text tag, and maybe bumping this tag's priority, but it does not work. Anyone interested should feel free to dig around in src/textview.c, maybe you will come up with a solution.
Thanks for trying, Andrej, and for your quick response! I think with "not currently possible" you mean something like "not easily doable". That's fine with me. I don't ask for big parts of the code to be rewritten to resolve one minor bug. At the same time, I would have preferred to leave it open. It's still a bug, not a feature.
