GPS wrong handling of CR / LF in a virtual Windows

[Achim <joachim.schroeer@web.de>]

Hello,

I have a very strange problem using the following configuration:

Gnat:	GNAT GPL 2011 / GPS 5.0.1
OS:	Virtual Windows XP using Virtual-Box on Host Mac-OS 10.6

The GPS editor does not handle CR/LF charaters correctly.
When the cursor is at the end of the line (behind the last displayed 
character) and enter is pressed, no empty new line appears, but all line 
numbers are incremented by one.
E.G. when the cursor is on the 5-th line in front of the 6-th line the 
numbers 6 AND 7 are displayed in the same character. After each pressing 
of enter another line-number is displayed in front of the next line, all 
in the same place, but no new empty line is inserted.

I tried all variations in the preferences-editor-Ada dialogs but without 
any success.

I've newer seen such behaviour, not on Mac-OS, Ubuntu or native Windows.

The same thing happens when already existing files are displayed in the 
editor. All existing empty lines are not shown.

The whole thing is a bit disturbing.
I would appreciate any hint.

Best regards.
