The CHM help files on Windows always open maximized. I would prefer they opened in a regular window instead, because the current behavior is annoying.

Fix: In Tools/msi/doc/doc.wxs line 34, change 'Show="maximized"' to 'Show="normal"'.

Does 'Show="normal"' cause the usual behavior of "do whatever it was doing when last closed"?  Does 'Show=' need to be specified?

Would you like to submit a PR?

Opening in normal size (i.e. randomly positioned somewhere on the screen) is equally annoying.

PR is welcome, but I won't be approving it. Someone else might.

Certainly doesn't need to be backported - this is not a bug.

I'll have to start with the ceterae again, won't I? OK, since you asked:

Ceterum censeo: This behavior could have been easily adapted to differing local requirements if MSI had been used as the distribution package format by appropriately transforming  the Shortcut table at install time, but burn bundles do not expose an interface to apply transforms to individual component MSIs, needlessly disabling this unique advantage of the Windows Installer technology.

(Apologies to people who know Latin. Unless I'm really lucky here.)

Not sure if the tracker will let me close the bug myself; if it doesn't, know that I have tried.
