Visible code is not the actual code, maybe in conjunction with GIT or copy/paste

The number of files is quite low at the moment, because the project is in the starting phase. I do a commit and push every evening. At this moment I'm not sure whether GIT has to do with my problem (as I said), but maybe it has to to with it, because you say "does some glitchy things".

But DW is not slow at all (at least not because of GIT).

I don't know what answer you expect to this question. You could also ask "Why are you using Dreamweaver?".

The answer is: Because I can and because I want to. Or: Why not?

Sorry if this anwer seems rude to you, but again: What should I answer to this?

Yes, I'm 100% sure/I know that I saved the file to my local hard drive. Now the content is OK, of course, because I corrected it yesterday. But even if I would not have saved it correctly, the behaviour I saw should not happen. I will make a simple example of what I experienced (really only a example, I cannot  remember all steps and the exact code is too long and (I guess) not the problem).

1.) I wrote a code, let's say:

<?php

if (isset($var)) {

echo 'hello world';

}

?>

2.) I pushed it to GIT, closed DW.

3.) On the next day I opened the document again, marked $var and copy/pasted (Ctrl-C/V) it over "'hello world'". It did not work, the code was not pasted (tried it several times). So I manually did it and also added the line "echo 'hi';". The code was fine in the code view:

<?php

if (isset($var)) {

echo $var;

echo 'hi';

}

?>

4.) I closed the document and opened it again immediately and saw something like this:

<?php

if $var$var$var$var(isset($var)) {

echo 'hello world';

}

?>

echo 'hi';

I think this describes the chaos I got. Again, this is only an example and NOT an instruction how to reproduce it. I only want to make clear what I mean.
