Thanks for the suggestion...didn't work though.
Winamp actually behaves similarly - if you have it minimized, and then right-click on the taskbar tab and select Close, then when you open it next time, it opens minimized. But they have a fix - just make the .ini file 'Read Only' and that's that.
I tried that with Screenshot Captor's .ini, which DID work, but also gave me an error every time as it loaded: Cannot Save, or something like that.
Oh well...I'll learn to live with it, it's a good app overall...
