Some symbols not printed?

Hi there,
I've build my own database connection class with a debug function. If the debug function is on, it should generate some comments in the html file. All works well. This is my source:
But when I run the get_var function on my local server (Apache) and view the page with Mozilla, I get these lines of comment:
<!-- DB Connection: mobileschool on localhost -->
<!-- Query: SELECT pagetitle FROM pagetitles WHERE pageid=1 AND language='NL' -->
<!-- Query successful: 0 query ID-->
-- get_var: SELECT pagetitle FROM pagetitles WHERE pageid=1 AND language='NL' successful query -- ID: 0 -->
<!-- Iterating through resultset -->
As you see, the <! is missing in front of get_var. Viewing the page with IE, or placing it on a remote server and viewing it both with IE and Mozilla gives me the missing <! (so the line is hidden from normal view).
Is there some strange setting like: 'hide random <! characters for Mozilla Browsers' in Apache that I am unaware of?
tnx!
