I have been taking screenhots with Wisdom Soft 4.0. Recently, When I take a picture in FS, the plane and the terminals only appear about 25% of the time. Don't know what's happening.
Bring up the panel, you may have the "lag" time set too long. I have mine at 1 second., it will still hesitate.
I don't use that software I use Screenhunter. All I can say is try and save them as .BMP and then resave them via Infanview as .JPEG. You will get better pictures.
