If you were a "developer" in any real sense you might just be questioning the qualifications of the 'cracker' and whether the crack was not faulty.....
Here's the evidence so far...
People with legitimate Windowblinds [example - me] did not have an issue...today, yesterday, or any other day.
People with an illegitimate Windowblinds ...with crack applied [example - you] DID have an issue.
To 'cloud' this issue a little, there will always be a legitimate user somewhere who has an unrelated issue, only contemporaniously coincidental. [example - person who mentioned a trial AV proggy].
Now...
It all means there are actually TWO programs on your machine Windowblinds, and the crack for it.
As seen by MY experience/example, Windowblinds didn't cause me harm, ergo it is NOT the culprit.
Guess what?
That leaves the crack as the fault [bit of a pun, there].
I say.....run off now....and sue the pants off that cracker.
Then....here's a trick....
Purchase a legit copy of Windowblinds....and enjoy that which you apparently WANT to.....and WITHOUT fear of kiddie-coding going wrong.
On a similar note....please remember that the skins you wish to apply FOR Windowblinds were created freely [mostly] for LEGITIMATE users of the product. The skinners wholly support Stardock's application and will not be all that happy having them available to unconscionable thieves.
This is one reason we tend to deny access to Wincustomize.com from people who profess to be using Stardock warez...
