I have a bug and im not sure whats causing it, im using 4.1.01b
Each time i go to capture a window or desktop, it will bring up the preview (in the case of send. In the case of a capture and save, it just captures and brings up the save-as, then the preview
I have all the options on the preference screen unchecked and my save to path is on a directory on d:\
Also you cant set the directory as the root of a drive, ie d:\ since it automatically puts a second trailing slash
I had a previous version before i formatted which worked fine, i cant remember what version it was though
Hope this info helps
