3. Select all.
4. Open Format menu and choose Capitalize.
5. Go to line 1001 to see how corrupted text appear.



Any idea to explain what happen?

For my test, I used the following pseudo-latin text without parenthesis:
(Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor. Cras elementum ultrices diam. Maecenas ligula massa, varius a, semper congue, euismod non, mi. Proin porttitor, orci nec nonummy molestie, enim est eleifend mi, non fermentum diam nisl sit amet erat. Duis semper. Duis arcu massa, scelerisque vitae, consequat in, pretium a, enim. Pellentesque congue. Ut in risus volutpat libero pharetra tempor. Cras vestibulum bibendum augue. Praesent egestas leo in pede. Praesent blandit odio eu enim. Pellentesque sed dui ut augue blandit sodales. Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia Curae. Aliquam nibh. Mauris ac mauris sed pede pellentesque fermentum. Maecenas adipiscing ante non diam sodales hendrerit.)

Like Normand, after try many test, mainly duplication selected text, i see:
most often, Seems to 98,713 characters all is well! (minus/majus/duplication..drop.)
But if 98,714 (and above) of selected then you see the
problems coming appear. (for me berfore 98713 characters)
often depending on the end of your selection ..sometimes i see at 98714 f or fer or u or m or r or um and after the good duplication.

Note:idem bug, when i drag selcted (> 98713) from one HiEdit to another Hiedit!

Note:
during these tests; among the multiple control Duplication/Z/Y
many inconsistencies visual after ^z not good for eyes but after enlargement/reduction the police it's recovering 'good' visual Perhaps this slight problem graphique is related.

good reception at all
