I came just from Skitch control bar: Help/technical support/ and this is how landed here !! I received not one tkt number, although before this current procedure, from within the,receive d a poped-up msg where I informed the issue. However I did receive not one TKT nbr..skitchenvironment it did crash twice or mor times , and I I reinstalled then a new version (MAC), and the problem changed : the reinstalled skitch ( for MAC) doesn't pick up screenshots . In the event of not being responded, I am giving up and trying to reinstall again , I this doesn`t work I will use another software and post my recent impressions to other user s in internet.
