[TYPO3-english] Cooluri drive me crazy: CSS broken

[mr7_0 at yahoo.it]

Hi,

first of all, sorry for my bad english...

I used 
cooluri many times in many sites without no problems, but days ago i 
acquired a new client with a typo3 website with cooluri installed but 
with very strange problem:

sometimes, random, some pages render 
with broken css (not all css are loaded). If i delete the corresponding 
url in cooluri link cache and regenerate the same page, the problem 
disappear and it's fine.
That problem is random on the whole site and repetitive.
I
 noticed in the params string stange values like: L=5%5%5%5%... or 
L=adwwihoefoj&id... or L=/////////////... thats value are for sure 
the problem for the page generation.
I tryed many configuration in xml but nothing. I check every step in cooluri configuration...

Did anyone had this kind of problem?

Jan, please help me!!!!

Thanks in
 advance to all list
