Unwanted pasting file path in my documents

HI
I am using Debian Testing 64 with Gnome.

I use Quanta for all my web site developments (and I love it)
I have just one problem  and I wonder if anybody is familiar with this ?
If so maybe they could tell me if I am doing something wrong or if its a 
bug and can it be fixed ?

I am plagued by pesky unwanted  recurrent pasting of the current file 
path into my working document, such as:

file:///media/samba/STMARTIN/www/domainenaudet/flash/include/spop3.inc
Etc ...

You can imagine that I have to check all my files very good for this 
before putting them online, its time consuming and is starting to get me 
down!

I have retraced my steps, I do quite a bit of cut and paste, working 
with php and html code, but I can't  figure how it happens, there does 
not seem to be a pattern , I have checked the short cut keys in Quanta 
config but did not see any thing.
I mainly use:
CTRL V
CTRL P
CTRL D
ALT TAB
CTRL TAB
Thats it..
None of these shortcuts cause this..

Thanks for any help.
Philip
