T. Lee DAVIDSON reported a new bug.

Summary
-------

Trying to drag-highlight text on line greater in width than main edit view is virtually impossible due to auto-shifting of edit window view.

Type             : Bug
Priority         : Low
Gambas version   : 3.8
Product          : Development Environment


Description
-----------

Supposing that the width of the main code editing window is 150 characters wide, a line with a length greater than that will cause a horizontal scroll bar to appear. Dragging the scroll bar to view the end of the line also allows some characters in columns less than 150 to still be displayed. Fine. No problem.

The issue arises when, while still viewing the end of the line, one attempts to select any visible text that is in a column less than 150 by dragging across it. The view is automatically shifted to show the beginning of the line and the select attempt is thwarted with unwanted characters selected. The view, unfortunately, also does not automatically scroll toward the end of the line when dragging past the right edge of the view port also disallowing selecting of text in that particular region.
