FIXED: Hang on ctrl+home after ctrl+End

[Qihe Pan]

On my another, "toy" machine with Windows 10 (Pentium 1.1 GHz, though probably overclocked a tad, and 4 Gb RAM), I was able to hang RJ TextEd (16.20, installed) only while counting substrings. Simple loading given file was quite quick, and changing highlighter to "Log" took like 10 sec. Even with this highlighter on, Ctrl-Home/Ctrl-End were acting instantaneously.

Thank you for your time and patience in testing!

Fixed in next release (v16.21 beta 3). It only happens when the document map is visible

Great! Thank you for all your effort!
